Question 1

In the following question, a sentence has been given in Active Voice. Out of the four alternatives suggested, select the one which best expresses the same idea in Passive Voice: "Had she worked hard she would have won the gold medal."

Accepted Answer

Introduction / Context:This question tests your understanding of transforming a conditional sentence from active voice to passive voice while keeping tense and meaning unchanged. The original active sentence is "Had she worked hard she would have won the gold medal." It is a conditional sentence that talks about an unreal past situation and its unreal result. You must choose the passive form that preserves this structure.Given Data / Assumptions:Active sentence: "Had she worked hard she would have won the gold medal."The structure is equivalent to "If she had worked hard, she would have won the gold medal."We need a passive version in which "the gold medal" becomes the subject.The logical time frame is past unreal, shown by "would have won".Options vary in their use of will, would, and conditional clause form.Concept / Approach:To change an active sentence to passive voice, the object becomes the subject, and the main verb changes into "be" plus past participle. In conditional sentences of the third type (unreal past), the pattern is "would have + past participle". In passive, this becomes "would have been + past participle". Therefore, "would have won the gold medal" changes to "the gold medal would have been won by her". The conditional clause "Had she worked hard" remains unchanged.Step-by-Step Solution:Step 1: Rewrite the sentence in full conditional form: "If she had worked hard, she would have won the gold medal."Step 2: Identify the object in the main clause: "the gold medal". This will become the subject in the passive sentence.Step 3: Convert "would have won" to passive: "would have been won".Step 4: Place "the gold medal" at the beginning and add the agent phrase "by her".Step 5: Keep the conditional clause "Had she worked hard" intact, giving "The gold medal would have been won by her had she worked hard."Verification / Alternative check:Check tense and meaning: The original sentence talks about a past situation that did not happen. The passive version "The gold medal would have been won by her had she worked hard" still clearly refers to a past unreal outcome. Both versions share the same implied meaning: she did not work hard, so she did not win the medal. Using "will have been won" would wrongly shift it to future perfect, which does not match the original conditional sense.Why Other Options Are Wrong:Option A ("will have been won"): Uses future perfect, which is incorrect for a past unreal conditional.Option C: Changes the conditional clause to "if she worked hard", which is more like a general or present unreal condition, not the specific past unreal one given.Option D: Combines "will have been won" with "if she worked hard", giving mixed and incorrect time reference.Option E: "Had been won by her if she worked hard" is grammatically clumsy and does not maintain the correct conditional structure.Common Pitfalls:Students often ignore the subtle difference between "will" and "would" in conditional sentences. In third conditional structures, "would have" is essential, and when converting to passive, you must keep "would have been" not "will have been". Another frequent mistake is to alter the conditional clause unnecessarily. Focus on changing only the main clause to passive while preserving the overall sentence pattern.Final Answer:The correct passive voice transformation is "The gold medal would have been won by her had she worked hard."

Question 2

In the following question, a sentence has been given in Active Voice. Out of the four alternatives suggested, select the one which best expresses the same idea in Passive Voice: "They cooked the food and sent it to the orphanage."

Accepted Answer

Introduction / Context:This question checks your ability to convert a sentence with two actions in sequence from active voice to passive voice without losing any information. The original active sentence is "They cooked the food and sent it to the orphanage." You must find the passive version that clearly mentions both actions and keeps the meaning intact.Given Data / Assumptions:Active sentence: "They cooked the food and sent it to the orphanage."Subject: "They".Object: "the food" (later referred to as "it").Actions: cooked the food, then sent the cooked food to the orphanage.Tense: Simple past.Concept / Approach:In passive voice, the object becomes the subject. We also need to represent both actions: cooking and sending. The food is the thing that was cooked and then sent. In passive, we can combine the two verb phrases as "The food was cooked and sent to the orphanage by them." This keeps the simple past passive form "was cooked" and "was sent" compactly combined. It also retains the information about the destination, "to the orphanage".Step-by-Step Solution:Step 1: Identify the object that will become the new subject: "the food".Step 2: Convert "cooked" to passive: "was cooked".Step 3: Recognise that "sent it to the orphanage" refers to the same food, which we now treat as the subject. Convert this to passive: "was sent to the orphanage".Step 4: Combine both passive verbs in a natural way: "The food was cooked and sent to the orphanage."Step 5: Add the agent phrase "by them" at the end: "The food was cooked and sent to the orphanage by them."Verification / Alternative check:Compare the original and the chosen passive sentence. Original: "They cooked the food and sent it to the orphanage." Passive: "The food was cooked and sent to the orphanage by them." Both versions mention cooking the food and sending it to the orphanage, in that logical order. The tense remains simple past. The doer "they" is now expressed as "by them", which is standard passive construction. No details are lost.Why Other Options Are Wrong:Option A: "The cooked food was sent to the orphanage by them." This mentions sending but leaves cooking only as an adjective. It reduces focus on the first action and is less accurate than explicitly saying "was cooked and sent".Option C: "The food was sent to the orphanage by them." This completely omits the cooking action, losing essential information.Option D: "The food was cooked and sent by them." This does not mention the destination, so it drops the important detail "to the orphanage".Option E: Uses "was being sent", which shifts the tense to past continuous passive and misrepresents the simple past actions.Common Pitfalls:Students sometimes focus only on one part of a compound predicate and forget to convert both verbs. Another common mistake is to drop important information such as the destination or time. When you see two actions joined by "and", make sure your passive version gives a clear and complete picture of both actions, using parallel passive forms if possible.Final Answer:The best passive voice transformation is "The food was cooked and sent to the orphanage by them."

Question 3

In the following question, a sentence has been given in Passive Voice. Out of the four alternatives suggested, select the one which best expresses the same idea in Active Voice: "The room was cleaned."

Accepted Answer

Introduction / Context:This question tests basic conversion from passive voice to active voice when the doer of the action is not mentioned. The sentence given is "The room was cleaned." In passive sentences like this, the agent is either unknown or unimportant. You must select the active version that best preserves this meaning without adding extra information that is not present in the original sentence.Given Data / Assumptions:Passive sentence: "The room was cleaned."Subject in passive: "The room."Verb tense: simple past passive (was cleaned).No agent phrase such as "by me" or "by the cleaner" is given.Options include various active sentences with different subjects.Concept / Approach:When the passive sentence does not mention who performed the action, the most neutral active conversion uses an indefinite subject like "someone" or "they". This avoids adding specific information that is not in the original sentence. If we switch to "I" or "the cleaner", we introduce a new agent that the original sentence did not specify. Therefore, a generic subject is preferred for an accurate transformation.Step-by-Step Solution:Step 1: Identify the action and tense: "was cleaned" indicates simple past cleaning.Step 2: Recognise that the passive sentence does not tell us who cleaned the room.Step 3: To convert to active, we need a subject. A neutral way is to use "someone" if the doer is unknown.Step 4: Construct the active sentence: "Someone cleaned the room."Step 5: Compare this with the options and select the one that matches.Verification / Alternative check:Check meaning: "The room was cleaned" simply indicates that the cleaning took place. "Someone cleaned the room" also indicates that the cleaning took place, without specifying who did it. Both sentences are equivalent in terms of known information. If we choose "I cleaned the room", we now claim that the speaker is the cleaner, which the original sentence never stated. Hence, "Someone cleaned the room" is the closest active equivalent.Why Other Options Are Wrong:The cleaner cleaned the room: Introduces a specific agent "the cleaner", which is extra information not present in the passive sentence.The room should be cleaned: Changes both tense and meaning, suggesting a recommendation instead of completed action.I cleaned the room: Again adds a specific agent, the speaker, which the passive sentence did not mention.They clean the room: Uses simple present tense and suggests routine action, not a single completed cleaning in the past.Common Pitfalls:Many learners try to "guess" a logical agent such as "the cleaner" or "the maid" when converting passive to active. However, exam questions check faithfulness to the original sentence. Unless the agent is clearly specified, you should not add a new specific subject. Use "someone" or "they" to preserve the uncertainty.Final Answer:The best active voice version of "The room was cleaned" is "Someone cleaned the room."

Question 4

In the following question, a sentence has been given in Active Voice. Out of the four alternatives suggested, select the one which best expresses the same idea in Passive Voice: "Where were they playing the cricket match?"

Accepted Answer

Introduction / Context:This question checks your understanding of passive voice for interrogative sentences in the past continuous tense. The active sentence is "Where were they playing the cricket match?" You must transform it into passive voice while maintaining the same tense, aspect, and question structure.Given Data / Assumptions:Active sentence: "Where were they playing the cricket match?"Tense and aspect: past continuous (were playing).Subject: "they".Object: "the cricket match".Question word: "Where".Concept / Approach:To convert an interrogative from active to passive, you need to keep the question word at the beginning, and change the auxiliary verb and main verb appropriately. The object "the cricket match" becomes the new subject. Past continuous active "were playing" becomes past continuous passive "was being played". Because "the cricket match" is singular, we use "was being". The basic pattern is: Where + was + subject + being played?Step-by-Step Solution:Step 1: Identify the verb phrase in the active sentence: "were playing". It is past continuous.Step 2: Identify the object that will become the subject: "the cricket match".Step 3: Convert "were playing" to passive for a singular subject: "was being played".Step 4: Place the question word "Where" at the beginning, followed by "was", then "the cricket match", then "being played".Step 5: The resulting sentence is "Where was the cricket match being played?" which matches option D.Verification / Alternative check:Check that tense and meaning are preserved. Original: "Where were they playing the cricket match?" asks about the location of the ongoing match at a certain time in the past. Passive: "Where was the cricket match being played?" also asks about the location of that same ongoing match, but focuses on the match instead of "they". The time reference (past) and continuous aspect (being played) remain unchanged, so the transformation is correct.Why Other Options Are Wrong:Option A: "Where was the cricket match played?" changes the tense to simple past and removes the continuous aspect, suggesting a completed event rather than an ongoing one.Option B: Uses present perfect passive "has been played", which does not match the original past continuous sense.Option C: "Will be played" is future passive, completely changing the time reference.Option E: "Is being played" is present continuous passive, again wrong time reference.Common Pitfalls:Students sometimes lose the continuous form when converting to passive and mistakenly change "were playing" to "was played". Another typical error is to forget subject verb agreement when the object becomes singular. Always check tense (past, present, future), aspect (simple, continuous, perfect), and number (singular or plural) when forming passive forms, especially in questions with wh words like "where".Final Answer:The correct passive voice question is "Where was the cricket match being played?"

Question 5

In the following question, a sentence has been given in Passive Voice. Out of the four alternatives suggested, select the one which best expresses the same idea in Active Voice: "These things have been left here by an unknown customer."

Accepted Answer

Introduction / Context:This question asks you to convert a present perfect passive sentence into its active voice equivalent. The passive sentence is "These things have been left here by an unknown customer." You need to select the active version that preserves the same time reference, subject object roles, and meaning.Given Data / Assumptions:Passive sentence: "These things have been left here by an unknown customer."Passive subject: "These things".Agent: "an unknown customer".Verb phrase: "have been left" (present perfect passive).Location adverb: "here".Concept / Approach:In present perfect passive, the pattern is "have/has been + past participle". To convert to active, we move the agent "an unknown customer" to the subject position, and change the verb to present perfect active: "has left". The object becomes "these things". Thus, the active equivalent should be "An unknown customer has left these things here." This keeps the present perfect sense (an action recently completed with present relevance) and retains all details.Step-by-Step Solution:Step 1: Identify the agent in the passive sentence: "by an unknown customer".Step 2: Move this agent to the subject position in the active sentence: "An unknown customer".Step 3: Recognise that "have been left" is present perfect passive for plural subject "these things".Step 4: Convert it to present perfect active with singular subject "An unknown customer": "has left".Step 5: Place "these things" as the object and keep the adverb "here": "An unknown customer has left these things here."Verification / Alternative check:Compare meanings: "These things have been left here by an unknown customer" and "An unknown customer has left these things here" both indicate a recent action of leaving items at the location, with the doer unknown by name but grammatically present. The present perfect tense suggests a present connection, such as the things still being there. This match confirms that option B is correct.Why Other Options Are Wrong:Option A: "Leaves" uses simple present, suggesting a repeated or habitual action, which is not implied in the original sentence.Option C: Uses "have left" with singular subject "customer". This is a subject verb agreement error.Option D: "Has been left these things" is ungrammatical and reverses the roles incorrectly.Option E: "Left" uses simple past, losing the present perfect sense and present relevance of the action.Common Pitfalls:Students often mishandle present perfect when switching from passive to active by either changing tense or breaking subject verb agreement. Always match singular subjects with "has" and plural with "have", and keep the perfect aspect when needed. Also, make sure that the subject in the active sentence is the original agent after "by", and that the ex object retains its correct position and form.Final Answer:The correct active voice version is "An unknown customer has left these things here."

Question 6

In the following question, a sentence has been given in Active Voice. Out of the four alternatives suggested, select the one which best expresses the same idea in Passive Voice: "The authorities will reward you for your hard work."

Accepted Answer

Introduction / Context:This question tests simple future tense conversion from active to passive voice. The active sentence is "The authorities will reward you for your hard work." You need to find the passive version that keeps the same future time reference and clearly expresses that you are the receiver of the reward.Given Data / Assumptions:Active sentence: "The authorities will reward you for your hard work."Subject: "The authorities".Object: "you".Verb phrase: "will reward" (simple future).Extra phrase: "for your hard work".Concept / Approach:To convert a simple future sentence to passive voice, we use the structure "will be + past participle". The object "you" becomes the subject. So "will reward you" changes to "you will be rewarded". Then we add the agent "by the authorities" and keep the reason phrase "for your hard work". Therefore, the correct passive sentence is "You will be rewarded by the authorities for your hard work."Step-by-Step Solution:Step 1: Identify the object that will become the passive subject: "you".Step 2: Convert "will reward" to passive using "will be rewarded".Step 3: Place "you" at the beginning: "You will be rewarded".Step 4: Add the agent phrase "by the authorities".Step 5: Append the phrase "for your hard work" to preserve the cause of the reward.Verification / Alternative check:Check meaning: Original sentence promises a future reward given by the authorities to you because of your hard work. The passive sentence "You will be rewarded by the authorities for your hard work" expresses exactly the same promise, with the same future reference and the same cause. The change is only in focus: from the authorities to you as subject. This confirms that the transformation is correct.Why Other Options Are Wrong:Option B: Uses "would be rewarded", which expresses a conditional or less certain future, not the definite future indicated by "will".Option C: "The authorities will be rewarded by your hard work" reverses the roles, suggesting that authorities receive the reward, which changes the meaning.Option D: Has both wrong subject and "would" instead of "will".Option E: Uses present perfect passive "have been rewarded", which implies the action is already complete, not future.Common Pitfalls:One common error is to change "will" to "would" when moving to passive, which alters the degree of certainty. Another error is misplacing the agent and making the authorities the receivers instead of the givers. Remember the pattern: Simple future active "will + verb + object" becomes Simple future passive "object + will be + past participle + by + subject". Apply this mechanically when you are unsure.Final Answer:The correct passive voice transformation is "You will be rewarded by the authorities for your hard work."

Question 7

In the following question, a sentence has been given in Active Voice. Out of the four alternatives suggested, select the one which best expresses the same idea in Passive Voice: "People felt that the police were corrupt."

Accepted Answer

Introduction / Context:This question deals with an impersonal passive construction used with reporting verbs like "feel", "believe", or "say". The active sentence is "People felt that the police were corrupt." The agent "people" is indefinite and not very important, so English often uses a structure beginning with "It was felt that..." for the passive version. You need to identify the option that correctly expresses this transformation.Given Data / Assumptions:Active sentence: "People felt that the police were corrupt."Subject: "People" (indefinite group).Reported clause: "that the police were corrupt."Tense: simple past ("felt" and "were").The passive structure should normally avoid awkward phrases like "were felt".Concept / Approach:When the subject is a general group like "people" and the verb is one of opinion or feeling, English commonly uses an impersonal passive structure: "It was felt that ...", "It was believed that ...". This avoids clumsy constructions such as "the police were felt to be corrupt". The pronoun "It" serves as a grammatical subject, while the content clause "that the police were corrupt" carries the real information. The tense "was felt" corresponds to the simple past "felt".Step-by-Step Solution:Step 1: Identify verb and subject in the main clause: "People felt".Step 2: Recognise that "people" is an indefinite general subject that can be dropped in the impersonal passive.Step 3: Convert "felt" to passive using "It was felt that ...".Step 4: Keep the that clause unchanged: "that the police were corrupt."Step 5: Combine both to get: "It was felt that the police were corrupt."Verification / Alternative check:Compare meanings: "People felt that the police were corrupt" and "It was felt that the police were corrupt" both communicate that there was a general feeling or opinion of corruption regarding the police. The second version is more formal and passive, which is exactly what the question is asking you to produce. The time reference also remains simple past. Therefore, option A is correct.Why Other Options Are Wrong:Option B: "The police were felt to be corrupt" is grammatically possible but sounds awkward for standard exam English and focuses unnaturally on the police as subject of "felt".Option C: "Were being corrupt" changes the meaning to something more temporary and ongoing, which is not implied in the original sentence.Option D: "Were felt being corrupt" is ungrammatical.Option E: "It had been felt" moves the tense to past perfect, suggesting a time even earlier than the original simple past, which is not required.Common Pitfalls:Students frequently try to make the original object the new subject and use patterns like "The police were felt to be corrupt", following a mechanical rule. However, with verbs of opinion and vague subjects like "people", English strongly prefers the impersonal passive starting with "It". Recognising these verbs and patterns can help you avoid awkward and non standard structures in exam questions.Final Answer:The correct passive construction is "It was felt that the police were corrupt."

Question 8

In the following question, a sentence has been given in Active Voice. Out of the four alternatives suggested, select the one which best expresses the same idea in Passive Voice: "They found him lying dead on the roadside."

Accepted Answer

Introduction / Context:This question tests your skill in converting a sentence with an object complement and a participial phrase from active to passive voice. The active sentence is "They found him lying dead on the roadside." Here, "him" is the object and "lying dead on the roadside" describes his state when he was found. The passive version must keep this description natural and grammatically correct while making "he" the subject.Given Data / Assumptions:Active sentence: "They found him lying dead on the roadside."Subject: "They".Object: "him".Verb: "found" (simple past).Complement phrase: "lying dead on the roadside".Concept / Approach:When converting to passive, "him" becomes "he", and the verb "found" becomes "was found". The participial phrase "lying dead on the roadside" should stay close to "he" to avoid awkwardness or ambiguity. The natural passive sentence is "He was found lying dead by the roadside." Note that "by the roadside" is the standard phrase, and "lying dead" remains as a present participle describing his condition at the time he was found.Step-by-Step Solution:Step 1: Change the object "him" into the subject pronoun "he".Step 2: Convert the verb "found" into passive simple past: "was found".Step 3: Attach the participial phrase "lying dead" to the new subject to preserve the meaning: "He was found lying dead".Step 4: Change "on the roadside" to the more natural "by the roadside" in passive construction.Step 5: Combine everything to get the full sentence: "He was found lying dead by the roadside."Verification / Alternative check:Compare meanings: Original sentence indicates that when they found him, he was lying dead, and the location was the roadside. The passive version "He was found lying dead by the roadside" conveys exactly the same picture, with the same time reference and conditions. The only change is that the doers "they" are not mentioned, which is common in passive voice when the doer is either unknown or not important.Why Other Options Are Wrong:Option A: "The roadside found him lying dead" is absurd because the roadside cannot perform the action of finding.Option B: "He was lying dead found by the roadside" is clumsy and ungrammatical in normal English.Option C: "Lying by the roadside, he was found dead" is close in meaning, but the placement of "dead" after "found" slightly shifts focus and is less direct than the original structure.Option E: "He found lying dead by the roadside" is incomplete and ungrammatical because it lacks an auxiliary verb "was".Common Pitfalls:Students sometimes try to change word order without adjusting auxiliary verbs, leading to incomplete passive forms. Others might create unidiomatic phrases like "was lying dead found". Always remember that in passive voice you must have a correct form of "be" plus a past participle, and any participial phrase describing the object should remain close to the subject in the new sentence for clarity.Final Answer:The correct passive voice sentence is "He was found lying dead by the roadside."

Question 9

In the following question, a sentence has been given in Active Voice. Out of the four alternatives suggested, select the one which best expresses the same idea in Passive Voice: "Scientists generally believe that small islands would sink."

Accepted Answer

Introduction / Context:This question involves converting a reporting sentence with the verb "believe" from active to passive voice in a natural, formal style. The active sentence is "Scientists generally believe that small islands would sink." Examinations often prefer an impersonal passive structure for such sentences, beginning with "It is generally believed that ...". You must choose the option that correctly reflects this structure without distorting the meaning.Given Data / Assumptions:Active sentence: "Scientists generally believe that small islands would sink."Subject: "Scientists".Reporting verb: "believe" in simple present.Adverb: "generally".Reported clause: "that small islands would sink."Concept / Approach:For sentences expressing general beliefs or opinions, English typically uses an impersonal passive form which shifts focus away from the group of people and toward the belief itself. The pattern is "It is generally believed that ...". Here, "believe" in simple present becomes "is believed" in passive. The adverb "generally" is placed before "believed", and the original that clause remains unchanged. Adding "by scientists" is optional but often included in exam style sentences to show the original agent group.Step-by-Step Solution:Step 1: Identify the main clause: "Scientists generally believe".Step 2: Convert this to impersonal passive: "It is generally believed".Step 3: Optionally include the agent: "by scientists".Step 4: Attach the that clause exactly as it is: "that small islands would sink".Step 5: Form the complete sentence: "It is generally believed by scientists that small islands would sink."Verification / Alternative check:Compare the two versions. Active: "Scientists generally believe that small islands would sink." Passive: "It is generally believed by scientists that small islands would sink." Both express exactly the same idea: there is a general belief among scientists about the fate of small islands. The tense remains present, the adverb "generally" stays, and the subordinate clause with "would sink" is unchanged. This confirms that option D is correct.Why Other Options Are Wrong:Option A: "Small islands will sink is generally believed by scientists." This has incorrect word order and replaces "would sink" with "will sink", changing the nuance.Option B: "There is a general belief that small islands would sink." This removes explicit mention of scientists as the believing group. It is semantically close but not as precise as the required passive structure.Option C: "Small islands are believed to sink by scientists." This not only changes "would sink" to "to sink" but also sounds awkward in this context.Option E: "Scientists are generally believed that small islands would sink" is ungrammatical, because "believed" cannot take "scientists" as subject in this pattern.Common Pitfalls:Students often try to put the original object at the beginning and follow it immediately with "are believed", without checking whether the resulting sentence is natural and grammatically correct. In many reporting verb cases, the safest and most natural passive pattern is the impersonal "It is believed that ...". Recognising such patterns will help you avoid forced or incorrect word orders in the exam.Final Answer:The correct passive voice sentence is "It is generally believed by scientists that small islands would sink."

Question 10

In the following question, a sentence has been given in Active Voice. Out of the four alternatives suggested, select the one which best expresses the same idea in Passive Voice: "Should you ever tell a lie?"

Accepted Answer

Introduction / Context:This question deals with passive voice transformation for a yes or no question in the modal form. The active sentence is "Should you ever tell a lie?" which is a moral question using the modal "should". You are asked to find the passive version that expresses the same idea without adding extra subjects like "one" or "everyone", and with natural word order.Given Data / Assumptions:Active question: "Should you ever tell a lie?"Modal: "should".Subject: "you".Object: "a lie".Adverb: "ever".We need to convert to passive while preserving the moral sense.Concept / Approach:When a modal like "should" is used, passive voice is formed using the pattern "should + be + past participle". The object "a lie" becomes the subject in passive. The adverb "ever" is usually placed between the modal and the main verb, giving "should ever be told". Therefore, the natural passive question becomes "Should a lie ever be told?" which keeps both the modal and the adverb in correct positions and maintains the moral, general sense.Step-by-Step Solution:Step 1: Identify the object that will become the subject: "a lie".Step 2: Recognise that "should tell" in active will become "should be told" in passive.Step 3: Place the adverb "ever" between "should" and "be told", as in standard English adverb placement.Step 4: Form the question structure: "Should a lie ever be told?"Step 5: Avoid unnecessary phrases like "by one" or "by everyone", since the original sentence is general and does not specify a particular doer.Verification / Alternative check:Compare meanings: "Should you ever tell a lie?" and "Should a lie ever be told?" both ask whether telling a lie is ever morally acceptable. The focus shifts from "you" to "a lie" but the general moral question remains the same. The passive version is more general, applying to anyone, which matches the typical use of "you" in moral questions in English, where "you" can mean "any person". Therefore, the passive transformation is accurate and natural.Why Other Options Are Wrong:Option A: "by one" is unnecessary and sounds unnatural; native speakers do not usually use this phrase in such moral questions.Option B: "by everyone" changes the meaning, suggesting that everyone together would tell the lie, which is not implied in the original sentence.Option C: "Should a lie be ever told?" has an awkward adverb position. The more natural word order is "ever be told".Option E: "Should ever a lie be told?" is also grammatically possible but sounds old fashioned; exams generally prefer the smoother modern order in option D.Common Pitfalls:Students often struggle with the placement of adverbs like "ever" in passive questions with modals. Remember that the most usual order is modal + adverb + be + past participle. Also, avoid overloading the sentence with unnecessary agents like "by one" unless the original sentence clearly implied such a subject. Keeping the passive version general often best matches the original general sense.Final Answer:The correct passive voice question is "Should a lie ever be told?"

Question 11

In the following question, a sentence has been given in Active Voice. Out of the four alternatives suggested, select the one which best expresses the same idea in Passive Voice: "The Principal promised the boys a holiday."

Accepted Answer

Introduction / Context:This question checks your ability to convert a simple past tense sentence with two objects into passive voice. The active sentence is "The Principal promised the boys a holiday." Here, "the boys" are the indirect object and "a holiday" is the direct object. Examinations usually expect you to make the indirect object the subject in passive, because it is the main focus of the action.Given Data / Assumptions:Active sentence: "The Principal promised the boys a holiday."Subject: "The Principal".Indirect object: "the boys".Direct object: "a holiday".Tense: simple past ("promised").Concept / Approach:When a verb takes two objects, English allows two possible passive patterns. For this type of exam question, the preferred pattern is usually to promote the indirect object to subject position: "The boys were promised a holiday by the Principal." Simple past active "promised" becomes simple past passive "were promised". This structure keeps the meaning clear and focuses on the receivers of the promise, which is natural in such sentences.Step-by-Step Solution:Step 1: Decide which object to make the subject. We choose "the boys" because they are the ones who receive the promise.Step 2: Determine the correct passive auxiliary for plural subject in simple past: "were".Step 3: Keep the main verb in past participle form: "promised".Step 4: Add the remaining object "a holiday" after the verb: "were promised a holiday".Step 5: Attach the agent phrase "by the Principal" at the end: "The boys were promised a holiday by the Principal."Verification / Alternative check:Compare the original with the passive version. Original: "The Principal promised the boys a holiday." Passive: "The boys were promised a holiday by the Principal." Both express that the Principal gave a promise to the boys about a holiday. The tense remains simple past. The shift in focus is from the Principal to the boys, which is appropriate for passive voice involving recipients.Why Other Options Are Wrong:Option A: "Have been promised" changes the tense to present perfect, which suggests the promise is very recent and still relevant, not simply an event in the past.Option B: "Had been promised" uses past perfect, which implies a time before another past event, adding unnecessary complexity not indicated by the original sentence.Option D: "Are promised" is present tense, again wrong time reference.Option E: "A holiday is promised by the Principal to the boys" is present tense and also less usual for this context; it changes both tense and emphasis.Common Pitfalls:Students often mishandle tense when moving from active to passive, especially in sentences with indirect and direct objects. Always identify the original tense first and keep it unchanged in your passive form. Also remember that with verbs like "give", "tell", and "promise", it is usually more natural in passive to make the receiver the subject, particularly when that receiver is a person or group.Final Answer:The correct passive voice version is "The boys were promised a holiday by the Principal."

Question 12

In the following question on Active and Passive Voice, transform the sentence "A police constable arrested the burglar just before dawn" into the correct passive form by choosing the best alternative.

Accepted Answer

Introduction / Context:This question tests your understanding of how to change a simple past tense sentence from the active voice to the passive voice in English grammar. In many competitive exams, such voice transformation items are common because they check whether you can preserve tense, meaning, and time expressions while changing the focus of the sentence. The original sentence focuses on the doer of the action, a police constable, whereas the passive form must correctly focus on the receiver of the action, the burglar. You also need to keep the time expression just before dawn in a natural and meaningful place in the sentence. The option that satisfies all these conditions is the correct answer.
Given Data / Assumptions:The key information can be summarised as follows.

The original active sentence is: A police constable arrested the burglar just before dawn.
The verb arrested is in the simple past tense.
Subject in the active sentence: a police constable.
Object in the active sentence: the burglar.
Time expression: just before dawn, which must be retained without changing the meaning.

Concept / Approach:To change an active sentence to the passive voice, we make the object of the active sentence the grammatical subject in the passive sentence. The verb is converted to the appropriate form of be plus the past participle of the main verb, keeping the tense unchanged. The subject of the active sentence is optionally retained in a by phrase, which shows the agent who performed the action. In this question the tense is simple past, so the passive auxiliary should be was or were, followed by the past participle arrested. The time expression just before dawn should be kept in a natural position, usually at the end of the sentence, and the logical meaning of the arrest should remain exactly the same.
Step-by-Step Solution:
Step 1: Identify the subject (a police constable), the verb (arrested), and the object (the burglar) in the active sentence.
Step 2: Move the object the burglar to the subject position of the passive sentence.
Step 3: Convert the verb arrested into the correct passive form for simple past: was arrested.
Step 4: Retain the agent a police constable in a by phrase and keep the time expression just before dawn at the end: The burglar was arrested by a police constable just before dawn.
Verification / Alternative check:We can verify the correctness by mentally converting the passive sentence back into the active form. If we start from The burglar was arrested by a police constable just before dawn and ask who performed the action and whom it affected, we get the original relationship: a police constable arrested the burglar just before dawn. The tense remains simple past, the meaning is unchanged, and the time expression is preserved. This confirms that the transformation is correct. Any variation that changes the tense, swaps subject and object, or alters the time reference is grammatically or logically incorrect.
Why Other Options Are Wrong:Option A uses is arrested, which is simple present, so it does not match the simple past arrested in the original sentence. Option C also uses is arrested and therefore has the same tense error. Option D completely changes the meaning by suggesting that the police constable was arrested by the burglar, which reverses the roles of subject and object. Option E uses past continuous was arresting, which again changes the tense and suggests an ongoing action rather than a completed one just before dawn. Thus, only option B accurately reflects the original sentence in passive voice.
Common Pitfalls:Candidates often forget to keep the tense the same when changing voice, and they mistakenly use is or was being instead of the correct auxiliary. Another common error is to accidentally swap the roles of subject and object, which can completely reverse the meaning. Some learners also misplace time expressions like just before dawn, resulting in sentences that sound unnatural. To avoid these problems, always identify subject, verb, object, and adverbials first and then systematically apply the passive voice rules. Check that the resulting sentence can be converted back to the original active form without any change of meaning.
Final Answer:The correct passive form is: The burglar was arrested by a police constable just before dawn.

Question 13

In this question on changing from Active to Passive Voice, choose the option that correctly expresses the sentence "The checker checks the admission tickets at the gate" in the passive form.

Accepted Answer

Introduction / Context:This item checks your ability to convert a simple present tense sentence from the active voice into the passive voice. The sentence describes a routine action at a gate where a checker examines admission tickets. In such questions, the examiner wants to see whether you can preserve the tense, meaning, and basic word order while correctly changing the grammatical focus from the subject to the object. Because the action happens regularly, the tense is simple present, and the passive form must also be in simple present. The correct answer will therefore use are checked along with the appropriate agent phrase.
Given Data / Assumptions:The important points in the sentence can be listed as follows.

Original sentence: The checker checks the admission tickets at the gate.
Tense: simple present (checks).
Subject: the checker.
Object: the admission tickets.
Adverbial of place: at the gate.

Concept / Approach:To form the passive voice from an active sentence, the object of the active sentence becomes the subject of the passive sentence. The main verb is changed into the correct form of be plus the past participle, and the original subject is usually introduced with by. In simple present tense, the be form is am, is, or are depending on the new subject. Here the new subject admission tickets is plural, so we must use are. The main verb checks becomes checked as a past participle. Finally, we keep the adverbial phrase at the gate and add the agent phrase by the checker to show who performs the action.
Step-by-Step Solution:
Step 1: Identify subject (the checker), verb (checks), object (the admission tickets), and adverbial (at the gate).
Step 2: Move the object the admission tickets to the subject position in the passive sentence.
Step 3: Choose the correct be form for simple present with a plural subject: are, and add the past participle checked to form are checked.
Step 4: Retain the place phrase at the gate and add the agent phrase by the checker to complete the passive sentence: The admission tickets are checked at the gate by the checker.
Verification / Alternative check:To verify, convert the passive sentence The admission tickets are checked at the gate by the checker back into active voice. The new subject becomes the checker, the verb becomes checks, and the object becomes the admission tickets, followed by at the gate. We arrive at The checker checks the admission tickets at the gate, which is exactly the original sentence. This confirms that tense, agent, and place have all been preserved correctly. Any option that changes the tense or removes essential information is unsuitable.
Why Other Options Are Wrong:Option B omits the agent the checker, which makes the sentence less complete, especially in an examination context where a full transformation is usually preferred. Option C uses will be checked, which changes the tense to simple future and therefore does not match the original simple present. Option D uses were checked, which is simple past and again changes the time reference. Option E uses have been checked, which is present perfect tense and suggests completion rather than a regular action. Only option A maintains the simple present tense and includes both the agent and the place phrase correctly.
Common Pitfalls:In voice transformation questions, students often ignore the tense and select any grammatically correct passive structure. However, correctness here means preserving tense as well as meaning. Another typical mistake is to forget the agent phrase when it is important to show who carries out the action. Learners also sometimes use wrong be forms such as is with plural subjects. Always check the number of the new subject and match it with the correct auxiliary. Then verify by mentally reversing the passive sentence back into the active one to see whether you recover the original statement.
Final Answer:The correct passive sentence is: The admission tickets are checked at the gate by the checker.

Question 14

In this English grammar question on voice, select the passive form of the sentence "People criticized him for not offering to pay for the damage".

Accepted Answer

Introduction / Context:This item focuses on changing an active sentence in the simple past tense into its correct passive form. The sentence describes people criticizing a person for not offering to pay for damage. In such questions, you must keep the time of the action, the meaning, and the grammatical aspect unchanged while shifting the focus from the doers of the action to the receiver of the action. Here, people is a general subject and not important as an agent, while him is the important part and needs to become the subject of the passive sentence. The correct option will therefore show him as the grammatical subject and will use the simple past passive construction was criticized.
Given Data / Assumptions:The sentence provides the following information.

Original sentence: People criticized him for not offering to pay for the damage.
Tense: simple past (criticized).
Subject: people (general, indefinite agent).
Object: him (the person who received criticism).
Reason clause: for not offering to pay for the damage, which must remain unchanged.

Concept / Approach:When converting an active sentence to passive voice, the object of the active sentence becomes the subject of the passive sentence. For simple past tense, the passive form uses was or were plus the past participle of the verb. Because the new subject is singular (he), the correct auxiliary is was. The phrase for not offering to pay for the damage should be preserved exactly, because it explains the reason for the criticism. Since the agent people is general and not important, it is normally omitted in the passive sentence, which is a standard practice in English when the doer is obvious, unknown, or unimportant.
Step-by-Step Solution:
Step 1: Identify the subject (people), the verb (criticized), and the object (him) in the active sentence.
Step 2: Move the object him into the subject position and change the pronoun to he, as required in subject position.
Step 3: Form the passive verb by using was (simple past of be for a singular subject) plus the past participle criticized, giving was criticized.
Step 4: Retain the reason clause for not offering to pay for the damage exactly as it is, resulting in: He was criticized for not offering to pay for the damage.
Verification / Alternative check:To verify, mentally transform the passive sentence back into active voice: He was criticized for not offering to pay for the damage becomes People criticized him for not offering to pay for the damage when we reintroduce a natural subject people and adjust pronouns. This matches the original sentence perfectly in tense and meaning. No additional aspect such as continuous or perfect is added, so the transformation is accurate. If any option introduces present tense or perfect aspect, it cannot be correct for a simple past original.
Why Other Options Are Wrong:Option A uses has been criticized, which is present perfect and does not match the simple past criticized in the original sentence. Option C uses is criticized, which is simple present, again changing the time reference. Option D is grammatically incorrect because is being criticizing mixes progressive aspect with the ing form of a verb that should appear as a past participle criticized. Option E uses was being criticized, which is past continuous passive and suggests an ongoing process rather than a completed act of criticism. Only option B gives a simple past passive form that preserves the original meaning.
Common Pitfalls:Students often confuse the different passive forms in past tenses, especially was criticized, has been criticized, and was being criticized. The safest method is to first identify the exact tense of the active verb and then apply the correct be form with the past participle. Learners also sometimes forget to adjust object pronouns to subject pronouns in passive sentences, but here the option already uses he correctly. Another mistake is to keep unnecessary agents like people when they are not needed, which can sound awkward in English. Always check that the passive sentence reads naturally and that the action is clearly completed in the correct time frame.
Final Answer:The correct passive sentence is: He was criticized for not offering to pay for the damage.

Question 15

For the following sentence on police harassment, choose the passive form that correctly expresses "The police is unduly harassing me".

Accepted Answer

Introduction / Context:This question tests your understanding of how to convert a present continuous sentence in active voice into an equivalent passive structure. The original sentence describes an ongoing action by the police that is happening at the present moment. The phrase is unduly harassing shows that the harassment is continuing. When we change such sentences into passive voice, we must preserve both the continuous aspect and the present time reference. The correct answer will therefore use am being harassed to show a present continuous passive construction.
Given Data / Assumptions:Important points from the sentence are listed below.

Original sentence: The police is unduly harassing me.
Tense and aspect: present continuous (is harassing).
Subject: the police (treated here as a collective noun).
Object: me (the person who suffers the harassment).
Adverb: unduly, which must be preserved to keep the idea of excessive harassment.

Concept / Approach:To form the passive of a present continuous sentence, we follow the pattern: subject + am/is/are + being + past participle. The object of the active sentence becomes the subject in the passive sentence. The continuous idea is shown through the word being, and the main verb appears as a past participle. In this case, me becomes the subject I in the passive sentence. The verb harassing in active becomes harassed in passive. Because I is singular, we use am as the form of be. The adverb unduly and the agent by the police need to appear in natural positions in the new sentence.
Step-by-Step Solution:
Step 1: Identify the subject (the police), verb phrase (is harassing), and object (me), along with the adverb unduly.
Step 2: Move the object me to the subject position and change it to I, which is the correct subject pronoun.
Step 3: Form the passive verb phrase for present continuous: am being harassed, using am for the subject I, being to mark the continuous aspect, and harassed as the past participle.
Step 4: Insert the adverb unduly before the past participle and add the agent phrase by the police to get: I am being unduly harassed by the police.
Verification / Alternative check:A quick verification method is to reconvert the passive sentence back to active voice. If we start from I am being unduly harassed by the police and reverse the roles, we get The police is unduly harassing me, which matches the original sentence. The tense is still present continuous, the idea of ongoing harassment is preserved, and the adverb unduly is in a natural position. This confirms that the passive conversion is correct in both grammar and meaning.
Why Other Options Are Wrong:Option A uses am unduly harassed, which is a simple present passive and does not show the continuous nature of the action. Option B uses was unduly harassed, which changes the tense to simple past and suggests a completed action in the past. Option C is ungrammatical because have being is not a correct verb phrase; it should be have been. Option E uses was being unduly harassed, which is past continuous passive and again shifts the time frame to the past. Only option D uses am being unduly harassed, correctly preserving the present continuous sense of the original sentence.
Common Pitfalls:Students frequently forget to include being in continuous passive forms, resulting in incorrect structures such as am harassed instead of am being harassed. There is also confusion about choosing the correct auxiliary verb for the new subject. Some learners ignore the difference between present and past forms and mistakenly select was when the original sentence is clearly in the present. To avoid these errors, first identify the tense and aspect (simple, continuous, perfect) of the active verb, and then apply the matching passive formula. Check that the new sentence still conveys an ongoing action if the original sentence does so.
Final Answer:The correct passive sentence is: I am being unduly harassed by the police.

Question 16

The following question tests recognition of the active form of a sentence originally written in the passive: "Had work been resumed by the labourers before the manager arrived?". Choose the correct active alternative.

Accepted Answer

Introduction / Context:Here the direction is to change a passive interrogative sentence in the past perfect tense into its correct active voice form. The original sentence, Had work been resumed by the labourers before the manager arrived?, uses a passive construction in question form. In competitive exams, such questions check whether you can recognise the original underlying active structure and reproduce it accurately, with the correct tense, auxiliary verbs, and word order. The target is a past perfect interrogative in active voice with labourers as the subject and work as the object, while the time clause before the manager arrived remains unchanged.
Given Data / Assumptions:The passive sentence gives the following information.

Original passive: Had work been resumed by the labourers before the manager arrived?
Tense: past perfect, as seen in had been resumed.
Grammatical subject in passive: work.
Agent in passive: by the labourers.
Time clause: before the manager arrived.

Concept / Approach:To change a sentence from passive to active voice, we reverse the process used for active to passive. The passive subject becomes the object in the active sentence, and the agent in the by phrase becomes the subject. In past perfect tense, the active form uses had plus the past participle of the main verb. In question form, had comes before the subject. Therefore, the structure we want is: Had + subject (the labourers) + past participle (resumed) + object (work) + time clause (before the manager arrived). The meaning of the sentence should remain that the labourers had already resumed work before the manager came.
Step-by-Step Solution:
Step 1: Identify the agent and the affected thing in the passive sentence. The agent is the labourers, and the affected thing is work.
Step 2: Make the labourers the subject of the new active sentence and move work into the object position.
Step 3: Keep the past perfect auxiliary had and the past participle resumed, and form the interrogative pattern Had the labourers resumed work.
Step 4: Attach the time clause before the manager arrived to obtain the full active interrogative: Had the labourers resumed work before the manager arrived?
Verification / Alternative check:To check the accuracy, we can convert the active sentence back into passive voice. Starting from Had the labourers resumed work before the manager arrived?, we move work to the subject position and place the labourers in a by phrase after the verb, giving Had work been resumed by the labourers before the manager arrived?. This matches the original question exactly, confirming that we have chosen the correct active alternative. The tense (past perfect), the sense of completed action before another past event, and the interrogative pattern are all preserved.
Why Other Options Are Wrong:Option A uses Have the labourers resumed work, which is present perfect, not past perfect, and so does not reflect the same time relation as had been resumed. Option C, Had they resumed the work before the manager came?, changes the subject to they and uses came instead of arrived, and it also sounds less precise; although similar in meaning, it does not match the structure that clearly corresponds to the given passive sentence. Option D introduces not, which changes the meaning and suggests that the workers perhaps did not resume work, whereas the original question is neutral. Option E uses Did the labourers resume work, which is simple past and does not show the sense of completion before another past event. Therefore, only option B is fully correct.
Common Pitfalls:Learners often miss tense distinctions between simple past, present perfect, and past perfect, and they may select an option simply because it sounds natural. Another common mistake is ignoring the negative word not or additional modifiers that can change the meaning. When dealing with passive to active transformations, always pay close attention to the auxiliary verbs had, has, have, and be sure that the new sentence can be converted back to the original form without any change of meaning. For interrogative sentences, make sure the auxiliary comes before the subject in both active and passive forms. Practising these patterns helps you answer such questions quickly in exams.
Final Answer:The correct active voice sentence is: Had the labourers resumed work before the manager arrived?

Question 17

This question checks your understanding of passive voice in interrogative sentences. Choose the correct passive version of "Should you have interrupted me while I was speaking?".

Accepted Answer

Introduction / Context:This question involves converting a modal perfect interrogative sentence from active to passive voice. The original sentence, Should you have interrupted me while I was speaking?, expresses criticism about an action that has already occurred and suggests that it was not appropriate. In the passive version the focus shifts from you, the doer of the action, to I, the person affected by the interruption. The key is to handle the modal should together with the perfect form have interrupted correctly in passive voice while preserving the sense of a completed but questionable action.
Given Data / Assumptions:The information in the sentence can be summarised as follows.

Original sentence: Should you have interrupted me while I was speaking?
Modal plus perfect construction: should have interrupted.
Subject: you (the person who performed the interruption).
Object: me (the person who suffered the interruption).
Time clause: while I was speaking, which must remain the same.

Concept / Approach:When a sentence with a modal and perfect aspect is changed into passive voice, the structure generally becomes: modal + have been + past participle. The object of the active sentence becomes the subject in the passive sentence. Thus, me changes to I in the subject position. The phrase have interrupted becomes have been interrupted. The rest of the clause, while I was speaking, is kept as it is because it describes the background activity during which the interruption took place. The sentence remains in question form, so the modal should appears at the beginning of the sentence in both active and passive constructions.
Step-by-Step Solution:
Step 1: Identify the subject you, the verb phrase should have interrupted, and the object me, plus the time clause while I was speaking.
Step 2: Move the object me into the subject position and convert it to I, which is the correct subject pronoun.
Step 3: Convert have interrupted into the passive form have been interrupted, and keep the modal should at the beginning to form Should I have been interrupted.
Step 4: Retain the time clause while I was speaking and complete the sentence: Should I have been interrupted while I was speaking?
Verification / Alternative check:To verify, mentally transform the passive sentence back to active voice. Starting from Should I have been interrupted while I was speaking?, we return to Should you have interrupted me while I was speaking? by reversing the subject and object roles and converting have been interrupted back to have interrupted. The meaning is the same, and the interrogative form with should remains unchanged. This shows that we have chosen the correct passive transformation.
Why Other Options Are Wrong:Option B, Should I be interrupted while I am speaking?, describes an ongoing or general situation rather than a completed action and changes the aspect from modal perfect to simple modal. Option C introduces by them, which changes the agent from you to an unspecified group, so it no longer corresponds directly to the original sentence. Option D, Should I not be interrupted while I am speaking?, expresses a demand or rule rather than criticism of a past action and completely changes the meaning. Option E reverses the roles and becomes another active sentence in which I interrupt you, which is the opposite of what the original sentence says. Therefore only option A is correct.
Common Pitfalls:Students often struggle with combining modals and perfect aspect in passive voice and sometimes forget the word been, writing forms like should have interrupted instead of should have been interrupted. Another common issue is changing the time reference or background clause, which must remain intact. When facing such questions, always identify the modal, the auxiliary have, and the main verb. Then apply the pattern modal + have been + past participle when forming the passive. Finally, check that the sentence still refers to a completed action that is being questioned or criticised, as in this example.
Final Answer:The correct passive form is: Should I have been interrupted while I was speaking?

Question 18

In this sentence transformation item, select the passive voice form of the question "Did they pay the clerks their salary on the first day of the month?".

Accepted Answer

Introduction / Context:This question asks you to change an interrogative sentence in simple past tense from active to passive voice. The original sentence, Did they pay the clerks their salary on the first day of the month?, talks about whether a completed payment took place at a specific time. In the passive version, the focus shifts from the people who pay (they) to the clerks, who receive their salary. The correct passive sentence must keep the simple past tense and the sense of a completed transaction that happened on the first day of the month.
Given Data / Assumptions:The sentence provides these key details.

Original sentence: Did they pay the clerks their salary on the first day of the month?
Tense: simple past, indicated by the auxiliary did and base verb pay.
Subject: they (unspecified payers).
Indirect object: the clerks.
Direct object: their salary.
Time expression: on the first day of the month.

Concept / Approach:For sentences with two objects, such as the clerks (indirect object) and their salary (direct object), we usually choose the indirect object as the new subject in the passive voice when the focus is on the people receiving something. The simple past passive form uses was or were plus the past participle paid. Because the new subject the clerks is plural, we use were. The question form in simple past passive is made by placing were before the subject. The rest of the sentence, including their salary and the time expression, should remain in a natural order that preserves the original meaning.
Step-by-Step Solution:
Step 1: Identify the subject (they), the verb (pay), the indirect object (the clerks), and the direct object (their salary), plus the time phrase on the first day of the month.
Step 2: Choose the clerks as the new subject for the passive sentence, because the question is clearly about whether they received payment.
Step 3: Form the simple past passive verb were paid by using were with the plural subject and the past participle paid.
Step 4: Place were before the subject to form a question and complete the sentence as Were the clerks paid their salary on the first day of the month?
Verification / Alternative check:To check, convert the passive sentence back to active: Were the clerks paid their salary on the first day of the month? becomes Did they pay the clerks their salary on the first day of the month? when we restore the subject they, use the simple past auxiliary did, and change paid back to pay. This matches the original sentence exactly, confirming that the tense, objects, and time expression all correspond correctly.
Why Other Options Are Wrong:Option B uses are, which is simple present, and changes the time reference from a specific past day to a general routine. Option C changes the subject to the singular clerk and the object to his salary, which alters the number and details of the original sentence. Option D uses were being paid, which suggests an ongoing process rather than the completed action asked about in the original question, and it is also incomplete because it lacks the time expression. Option E uses past perfect had been paid, changing the tense and introducing a prior time relation that is not present in the original simple past question. Only option A keeps the simple past passive structure and the complete meaning.
Common Pitfalls:One common problem is confusion between simple past and present forms in passive questions, especially when the auxiliary verb comes before the subject. Students sometimes focus only on the correctness of the passive structure and ignore the time reference. Another difficulty arises when there are two objects; candidates may try to convert the direct object into the subject even when the context focuses on people. To avoid this, first decide what the question is really about and then select the object that should become the new subject. Finally, always check whether the passive sentence can be accurately reversed into the original active form without loss of meaning.
Final Answer:The correct passive question is: Were the clerks paid their salary on the first day of the month?

Question 19

The sentence "The breakfast will have been finished by eight" is given in the passive voice. Choose the option that correctly expresses the same meaning in the active voice.

Accepted Answer

Introduction / Context:This item tests your ability to change a future perfect passive sentence into its corresponding active form. The original sentence, The breakfast will have been finished by eight, states that the action of finishing breakfast will be completed before or by a certain future time. In the active sentence the focus moves from breakfast, the thing acted upon, to the implied doers of the action, they. The correct option must therefore use a future perfect active construction that preserves the sense of completion by eight o'clock.
Given Data / Assumptions:The sentence provides the following elements.

Original passive: The breakfast will have been finished by eight.
Tense and aspect: future perfect passive (will have been finished).
Passive subject: the breakfast.
Agent: implied they, not explicitly stated in the sentence.
Time reference: by eight, showing a point in the future before which the action will be complete.

Concept / Approach:The future perfect passive form follows the pattern will have been + past participle. To convert this to active voice, we keep the future perfect structure but remove been and make the agent the new subject. The pattern becomes subject + will have + past participle. Here the natural active subject is they, representing the people who will eat or prepare the breakfast. The verb finished remains as a past participle after have. The phrase by eight is essential because it signals that the action will be completed not at a single moment exactly at eight but at some time before or up to eight o'clock. Thus, the correct active sentence must be They will have finished the breakfast by eight.
Step-by-Step Solution:
Step 1: Recognise that will have been finished is the future perfect passive form of the verb finish.
Step 2: Identify the implied agent, which we can express as they in the active sentence, even though it is not stated in the passive sentence.
Step 3: Convert will have been finished into the active structure will have finished and place it after the subject they.
Step 4: Keep the time phrase by eight unchanged and place the object the breakfast after the verb, forming They will have finished the breakfast by eight.
Verification / Alternative check:To verify, take the active sentence They will have finished the breakfast by eight and convert it back into passive voice. The object the breakfast becomes the subject, the future perfect active verb will have finished becomes the future perfect passive will have been finished, and the agent they is removed or placed in an optional by phrase. The resulting sentence is The breakfast will have been finished by eight, which matches the original. This confirms that the active option we have chosen is correct and preserves the meaning and time reference.
Why Other Options Are Wrong:Option A, They will finish the breakfast by eight, uses simple future instead of future perfect. Although close in meaning, it does not express the same emphasis on completion before a certain time. Option B, They will finish the breakfast at eight, changes both the tense and the preposition and suggests that completion occurs exactly at eight o'clock. Option D, They will be finishing the breakfast at eight, is future continuous and focuses on an ongoing action at that time, not a completed one. Option E, They have finished the breakfast by eight, uses present perfect and completely changes the time frame. Only option C correctly uses future perfect and preserves the by eight time expression.
Common Pitfalls:Many learners do not distinguish clearly between at and by when talking about time, even though the meanings differ. In perfect tenses, by is important because it indicates a deadline or upper limit for completion. Another frequent error is to ignore the presence of have been in a passive verb phrase and to choose a simple future form instead. When dealing with tenses and voice, always break complex verb phrases into components, identify the tense and aspect, and then apply the corresponding active or passive pattern. This method prevents confusion between simple future, future continuous, and future perfect.
Final Answer:The correct active voice sentence is: They will have finished the breakfast by eight.

Question 20

In this item on changing active to passive, choose the most appropriate passive version of the sentence "You might have given this information earlier".

Accepted Answer

Introduction / Context:This question concerns the conversion of a modal perfect sentence in active voice into passive voice. The original sentence, You might have given this information earlier, expresses mild criticism or suggestion that an action could have been completed at an earlier time. In passive voice the focus is placed on this information rather than on you. The correct passive structure must keep the modal might and the perfect aspect have given, while changing the verb phrase into a passive form that preserves the sense of possibility in the past.
Given Data / Assumptions:The sentence gives the following details.

Original sentence: You might have given this information earlier.
Modal plus perfect: might have given.
Subject: you (the person who could have provided the information).
Object: this information.
Adverb: earlier, indicating that the action could have been done at a previous time.

Concept / Approach:When a sentence with a modal and perfect aspect is changed into passive, the pattern is modal + have been + past participle. The object of the active sentence becomes the subject in the passive sentence. Here, this information becomes the new subject. The verb phrase have given must be converted to have been given, while the modal might remains unchanged. Because the criticism is general and the agent you is not important in the new focus, the passive sentence can omit the agent. The adverb earlier is preserved in its normal position near the end of the sentence.
Step-by-Step Solution:
Step 1: Identify the subject you, the verb phrase might have given, and the object this information, plus the adverb earlier.
Step 2: Move the object this information to the subject position in the passive sentence.
Step 3: Convert have given into the passive form have been given while keeping the modal might before it, producing might have been given.
Step 4: Retain the adverb earlier at the end of the sentence to form: This information might have been given earlier.
Verification / Alternative check:To verify, mentally return from the passive sentence to the active one. Starting with This information might have been given earlier, we can restore the agent you and convert have been given back to have given, getting You might have given this information earlier. This matches the original statement closely in meaning, tone, and time reference, confirming that the transformation is accurate. The sentence still implies that giving the information earlier was possible and perhaps desirable.
Why Other Options Are Wrong:Option B, This information could have been given earlier, uses could instead of might and slightly changes the nuance; while similar, exam questions typically expect the same modal to be preserved. Option C, This information was given much earlier, changes both the modal idea of possibility and the time reference, turning the sentence into a simple factual statement. Option D, This information might be given by you earlier, mixes present passive might be given with the adverb earlier and sounds unnatural. Option E, This information might be giving earlier, is grammatically incorrect because might be giving does not combine properly with earlier in this context. Therefore option A is the only fully correct passive version.
Common Pitfalls:Learners often replace one modal with another without realising that exam questions usually expect the exact modal element to be carried over. Another issue is confusion between perfect and non perfect forms in passive constructions, resulting in forms like might be given instead of might have been given. When handling such items, it is helpful to memorise the pattern modal + have been + past participle for passive sentences. Always check that the sense of possibility or criticism in past time is preserved and that the resulting sentence sounds natural in standard English.
Final Answer:The correct passive sentence is: This information might have been given earlier.
