Question 1

Sentence improvement — parallel auxiliary structure: 'has not been and can never be in the good books' (supply past participle after 'has').

Accepted Answer

Given sentenceHe has not and can never be in the good books of his employer because he lacks honesty.Concept/ApproachAfter the auxiliary 'has', a past participle must follow ('has been'). Maintain parallelism across the coordinated verb phrases: 'has not been and can never be …'Corrected spanhas not been and can never beWhy other options fail'has not and cannot be' → missing participle after 'has'.'has not and can never been' → wrong placement of 'been'.'No improvement' → leaves a grammar error.Final Answerhas not been and can never be

Question 2

Sentence improvement — pronoun case in compound subject: use the subject form 'Anil and I' after the clause 'When the examinations were over …'.

Accepted Answer

Given sentenceWhen the examinations were over Anil and me went to our native town.Concept/Approach'Anil and I' is the compound subject; therefore the pronoun must be in the subjective case ('I'), and by convention we place the first/third person before first person for politeness: 'Anil and I …'Eliminating options'me and Anil' → wrong case and order.'I and Anil' → awkward ordering.'No improvement' → keeps the error.Final AnswerAnil and I

Question 3

Sentence improvement — choose the precise adjective for timekeeping: prefer 'accurate' rather than 'correct/right/regular' for clocks: 'Our office clock is not as accurate as it should be …'

Accepted Answer

Given sentenceOur office clock is not so correct as it should be; it is usually five minutes fast.Concept/ApproachFor instruments, the natural adjective is accurate, meaning 'showing the correct time'.Correction'not so correct as' → more idiomatic as 'not as accurate as …'Why others are suboptimal'right' → informal and less precise.'regular' → refers to interval/consistency, not exactness.'No improvement' → retains weaker diction.Final Answeraccurate

Question 4

Sentence improvement — correct phrasal verb for the end of difficulties: choose 'blown over' (not 'blown out/up/away') in 'The cloud of misfortunes appears to have blown over.'

Accepted Answer

Given sentenceThe cloud of misfortunes appears to have blown out.Concept/ApproachThe idiom describing a problem subsiding is blow over. 'Blow out' usually refers to extinguishing a flame or bursting a tyre; 'blow up' is to explode; 'blow away' is to carry off.Correctionblown overFinal Answerover

Question 5

Sentence improvement — remove redundant complementizer and fix number/capitalization: prefer 'While we would like all Indian children to go to school …' over 'we would like that all Indian Children …'

Accepted Answer

Given sentenceWhile we would like that all Indian Children to go to school, we need to ponder why they do not.Concept/ApproachAfter 'would like', English takes an object + to-infinitive ('like someone to do something'). The complementizer 'that' is unnecessary here. Also use lower-case 'children' and concise phrasing.Correction'would like that all Indian Children to go' → 'would like all Indian children to go …'Why alternatives are weaker'that all the Indian children' → still keeps the incorrect 'that' construction.'if all the children of India' → changes meaning to a condition.'No improvement' → retains structural error and odd capitalization.Final Answerall Indian children

Question 6

Sentence improvement — Choose the most idiomatic and temporally accurate wording for this civics/history sentence: ‘‘In India today many of our intellectuals still talk in terms of the French Revolution and the Rights of Man, not appreciating that m…

Accepted Answer

Given dataIn India today many of our intellectuals still talk in terms of the French Revolution and the Rights of Man, not appreciating that much has happened since then.Concept/ApproachThe phrase ‘‘since then’’ requires the present perfect to connect a past reference point with relevance to the present. ‘‘has happened’’ correctly expresses completed change up to now.Step-by-step evaluationmuch has been happening — Present perfect progressive suggests ongoing activity, not a completed span of historical change; less apt.much had happened — Past perfect needs another past time anchor; none is provided.much might happen — Hypothetical future; contradicts ‘‘since then’’.No improvement — Retains the correct present perfect with ‘‘since then’’.Verification/AlternativeCompare: ‘‘Much has changed since then’’ (standard idiom). The given structure mirrors this pattern.Common pitfallsSwitching to past perfect without a second past reference point; overusing progressive aspect with historical summaries.Final AnswerNo improvement

Question 7

Sentence improvement — Polite conditional request form: choose the most natural modal construction to refine ‘‘I shall be grateful to you if you are of help to me now.’’ so the register is courteous and idiomatic.

Accepted Answer

Given dataI shall be grateful to you if you are of help to me now.Concept/ApproachIn polite requests, English favors ‘‘I would be grateful if you would help me (now).’’ The modal ‘‘would’’ signals courteous willingness/volition.Step-by-step evaluationhelp — Bare infinitive after ‘‘if you’’ is ungrammatical here.would help — Correct: ‘‘I shall/would be grateful if you would help me now.’’helped — Simple past after ‘‘if’’ implies unreal/remote condition; clashes with ‘‘now’’.No improvement — Leaves the clumsy ‘‘are of help’’; less idiomatic.Verification/AlternativeEqually natural: ‘‘I would be grateful if you could help me now.’’Common pitfallsUsing ‘‘are of help’’ instead of the direct verb ‘‘help.’’ Overlooking courtesy modal ‘‘would/could’’ in requests.Final Answerwould help

Question 8

Sentence improvement — Past perfect passive with medial adverb placement: refine ‘‘The logic of Berlin wall already had been undermined ...’’ by choosing the best adverb position to produce a formal, fluent clause before the main event.

Accepted Answer

Given dataThe logic of Berlin wall already had been undermined but when the news came through that the wall itself had been opened I jumped into a car.Concept/ApproachIn passive past perfect, stance adverbs like ‘‘already’’ most naturally appear between the auxiliary and the past participle: ‘‘had already been …’’. Among the provided options, the adverb placement in option (B) is the most idiomatic.Step-by-step evaluationhad been undetermined already — Adverb at end is possible but less elegant; rhythm is weaker.had already been undetermined — Preferred adverb slot; reads smoothly.had been already undetermined — Splits ‘‘been’’ and complement unnaturally.No improvement — Leaves the adverb before the auxiliary cluster; less natural.Verification/AlternativeStandard template: ‘‘Subject + had already been + past participle ...’’Common pitfallsMisplacing ‘‘already’’ so it disrupts auxiliary stacking; mixing aspects/voices.Final Answerhad already been undetermined

Question 9

Sentence improvement — Correct tense with a definite past-time marker: improve ‘‘Other countries have eradicated this disease ten years ago.’’ by selecting the appropriate simple past form for a time-adverbial ‘‘... years ago’’.

Accepted Answer

Given dataOther countries have eradicated this disease ten years ago.Concept/ApproachWith a specific past time (‘‘ten years ago’’), English requires the simple past, not the present perfect.Step-by-step evaluationeradicated — Correct simple past: ‘‘... eradicated this disease ten years ago.’’had eradicated — Past perfect needs a second, later past reference; not present.did eradicated — Incorrect auxiliary + past form combination; should be ‘‘did eradicate’’ if emphasis were needed.No improvement — Keeps wrong tense.Verification/AlternativeRule of thumb: ‘‘ago’’ → simple past.Common pitfallsOverextending present perfect with explicit past-time adverbials.Final Answereradicated

Question 10

Sentence improvement — Collocation and register: choose whether ‘‘Young men and women should get habituated to reading and writing about current affairs.’’ needs any change for formal correctness and clarity.

Accepted Answer

Given dataYoung men and women should get habituated to reading and writing about current affairs.Concept/Approach‘‘Get habituated to’’ + gerund is acceptable in formal English to suggest developing a steady habit. Alternatives either shift meaning or naturalness.Option analysisused — ‘‘get used to’’ is idiomatic but slightly more informal/colloquial than ‘‘get habituated to’’ in this register.prepared — ‘‘get prepared to’’ changes meaning from habit to readiness.trained — Implies an external trainer; not the intent.No improvement — Best preserves formal tone and intended sense.Verification/AlternativeAn equally fine rephrase is ‘‘cultivate the habit of reading and writing about current affairs.’’ The key is that no mandatory change is required.Final AnswerNo improvement

Question 11

Sentence improvement — Choose the correct aspect for a continuing action with ‘‘for more than 4 hours now’’: improve ‘‘The poor villagers have waited in the bitter cold for more than 4 hours now.’’

Accepted Answer

Given dataThe poor villagers have waited in the bitter cold for more than 4 hours now.Concept/ApproachDuration with ‘‘for ... now’’ indicates an action that started in the past and is still continuing. Use the present perfect continuous: ‘‘have been waiting.’’Option analysishave been waiting — Correct aspect and plural agreement with ‘‘villagers’’.had waited — Past perfect requires a later past anchor; not present.has been waiting — Subject–verb disagreement (singular vs plural).No improvement — Leaves suboptimal aspect.Verification/AlternativeTemplate: ‘‘They have been + V-ing for X hours now.’’Final Answerhave been waiting

Question 12

Sentence improvement — Remove double negative and fix quantifier: refine ‘‘The old man felled some trees in the garden with hardly no effort at all.’’ to standard affirmative English.

Accepted Answer

Given dataThe old man felled some trees in the garden with hardly no effort at all.Concept/ApproachStandard English avoids double negatives unless intended rhetorically. ‘‘Hardly any’’ is the correct quantifier with ‘‘hardly’’.Option analysishard effort — Reverses meaning.hardly any effort — Corrects the double negative and preserves sense.a hardly any effort — Articles do not precede ‘‘hardly any’’ in this structure.No improvement — Keeps the error.Verification/AlternativeRecast: ‘‘... with almost no effort at all.’’Final Answerhardly any effort

Question 13

Sentence improvement — Subordinate clause after ‘‘ensure that’’: select the best finite-clause completion of ‘‘The company goes to great length to ensure that employees ___ comfortable in their work environment.’’ so the result clause is natural and…

Accepted Answer

Given dataThe company goes to great length to ensure that employees can be comfortable in their work environment.Concept/ApproachAfter ‘‘ensure that’’, we typically use a straightforward indicative clause that states the assured state: ‘‘employees are comfortable.’’ The modal ‘‘can’’ implies mere possibility, not ensured outcome.Option analysisare comfortable — Best: expresses the guaranteed state the company aims to secure.will be comfortable — Future orientation; unnecessary and less idiomatic.should be comfortable — Moral desirability, not assurance.No improvement — Retains weaker ‘‘can be’’.Verification/AlternativeAlso idiomatic: ‘‘ensure a comfortable work environment for employees.’’Common pitfallsOver-using modals like ‘‘can/should’’ when a simple finite verb better matches ‘‘ensure that’’.Final Answerare comfortable

Question 14

Sentence improvement — Word order and the split infinitive in a directive: assess ‘‘I want you to clearly understand that excuses won't do’’ and decide if any rearrangement is required for modern standard English.

Accepted Answer

Given dataI want you to clearly understand that excuses won't do.Concept/ApproachSplit infinitives (‘‘to clearly understand’’) are widely accepted in contemporary English, especially when they improve clarity and rhythm. The pronoun placement ‘‘I want you to …’’ is also standard.Option analysisyou clearly to understand — Unnatural word order.you to understand clearly — Acceptable, but no need to move the adverb; current placement is fine.to clearly understand you — Changes the object (misleading meaning).No improvement — Best choice; modern, clear, idiomatic.Verification/AlternativeAlternative: ‘‘I want you to understand clearly ...’’ (also correct). The given version is not erroneous.Common pitfallsTreating all split infinitives as wrong—this is a myth; clarity takes precedence.Final AnswerNo improvement

Question 15

Sentence improvement — Passive voice for penalties: determine whether ‘‘He was fined for careless driving.’’ already uses the correct passive construction and therefore requires no change.

Accepted Answer

Given dataHe was fined for careless driving.Concept/ApproachOfficial penalties are commonly reported in the passive: ‘‘was fined’’. It is concise, formal, and correct.Option analysisgot fined — Colloquial; less formal.fined — Bare past-participial fragment if used alone; the given sentence already has a complete passive clause.was to be fined — Indicates future-in-the-past intention, not actual imposition.No improvement — Keeps the proper passive.Verification/AlternativeActive alternative: ‘‘The court/police fined him for careless driving.’’ Passive is perfectly natural here.Common pitfallsAssuming ‘‘got + past participle’’ is acceptable in formal exam English; prefer be-passive for penalties.Final AnswerNo improvement

Question 16

Sentence improvement — choose the most appropriate idiom: replace the phrase 'by far' with the broader, summary expression 'by and large' to read, 'Although India is still by and large a poor country, it can become rich if its natural and human reso…

Accepted Answer

Given sentenceAlthough India is still by far a poor country, it can become rich if its natural and human resources are fully utilised.Concept/ApproachWe are improving word choice/collocation. 'By far' is an intensifier meaning 'to a great degree', which does not match the concessive nuance here. The sentence wants an overall characterization — 'on the whole' — which is conveyed by the idiom by and large.Option analysis• by and large = 'on the whole; generally.' Fits after 'still' to mean 'still generally a poor country'.• 'few and far between' = rare/scarce; illogical here.• 'by and by' = soon/after a while; wrong meaning.• 'No improvement' keeps a less suitable intensifier.Final Answerby and large

Question 17

Sentence improvement — remove the illogical double cause ('reason' + 'because') and use a clean complement: 'The reason why he wrote the letter was that he could not contact him over the phone.'

Accepted Answer

Given sentenceThe reason why he wrote the letter was because he could not contact him over the phone.Concept/ApproachAvoid double causatives like 'reason … because'. Standard English uses: 'The reason … was that …' or simply 'He wrote the letter because …'.Option analysis• why he wrote the letter was that → correct complementizer 'that' after 'was' avoids redundancy.• 'why … was since' → 'since' is causal but sounds clumsy in this slot.• 'for which … because' → repeats cause ('for which' + 'because'); ungrammatical.• 'No improvement' → retains the redundancy.Final Answerwhy he wrote the letter was that

Question 18

Sentence improvement — correct phrasal verb: use the reflexive idiom 'look after himself' in 'As he is past his teens now, he can look after himself.'

Accepted Answer

Given sentenceAs he is past his teens now, he can look for himself.Concept/ApproachThe intended meaning is 'take care of himself'. The set phrase is look after oneself, not 'look for oneself' (which means 'search for oneself', illogical).Option analysis• after → 'look after (himself)' is correct.• 'to'/'around' → wrong particles for this meaning.• 'No improvement' keeps a semantic error.Final Answerafter

Question 19

Sentence improvement — prefer the precise noun 'space': 'There is no more space for you in this compartment.'

Accepted Answer

Given sentenceThere is no more room for you in this compartment.Concept/ApproachIn transport contexts (train/coach compartment), 'space' is idiomatic for available capacity. 'Room' is acceptable in general, but 'space' is crisper and collocates better with seats/standing areas.Option analysis• there is no more space → natural collocation.• 'no more seat' → number mismatch (should be 'seats'); also too specific.• 'accommodation' → formal and odd here.• 'No improvement' → less idiomatic.Final Answerthere is no more space

Question 20

Sentence improvement — correct preposition with 'protest': use 'protest against' an action: 'Most donors would seriously protest against any effort to extrapolate from such limited data.'

Accepted Answer

Given sentenceMost donors would seriously protest any effort to extrapolate from such limited data.Concept/ApproachWhen the object is an action/proposal, the collocation is protest against (e.g., protest against a decision). 'Protest to' is used with a person, and 'protest at' is less common/BrE-specific for places or events.Correctionprotest against any effort …Final Answerprotest against
