Question 1

English grammar error-spotting (sequence of tenses in reported belief/expectation): Choose the single erroneous part; select ‘‘No error’’ only if all is correct: ‘‘He was sure / that he should / win the Prize. / No error.’

Accepted Answer

Concept/Approach After a past reporting verb of certainty/belief (‘‘was sure’’), the natural backshift for a future-in-the-past is ‘‘would’’: ‘‘that he would win …’’. ‘‘Should’’ does not express simple futurity here. Correction ‘‘He was sure that he would win the prize.’’ Notes Also standardize capitalization: ‘‘prize’’ is not a proper noun unless part of a title (e.g., ‘‘the Nobel Prize’’). Final Answer that he should

Question 2

English grammar error-spotting (‘‘too … to’’ construction; intensifier usage): Read the sentence and pick the erroneous segment only if present; otherwise choose ‘‘No error’’: ‘‘He is / too intelligent / to make a mistake. / No error.’

Accepted Answer

Grammar check The idiom ‘‘too + adjective + to + verb’’ can mean ‘‘so … that not’’; here it conveys ‘‘so intelligent that he does not make mistakes’’. The construction is acceptable and idiomatic. Common pitfalls Assuming ‘‘too … to’’ is always ungrammatical—what matters is the intended negative result implied. Final Answer No error.

Question 3

English grammar error-spotting (third conditional form—‘‘would have’’ + ‘‘if’’-clause with past perfect): Identify the single erroneous segment: ‘‘He fell from a running train / and would have died / if the villagers did not get him admitted in the …

Accepted Answer

Given data Main clause: ‘‘… would have died’’ → counterfactual past result. If-clause: uses simple past ‘‘did not’’ + awkward verb choice/preposition. Concept/Approach In a third conditional, pair ‘‘would have + past participle’’ with an if-clause in the past perfect: ‘‘if … had not …’’ Also prefer ‘‘admitted to hospital’’ for the preposition. Step-by-step correction Use past perfect in the condition: ‘‘if the villagers had not got/gotten him admitted …’’Preposition: ‘‘admitted to the nearby hospital’’. Common pitfalls Mixing ‘‘would have’’ with ‘‘if + did’’. Using ‘‘in hospital’’ vs ‘‘to hospital’’—both can be correct in different senses; here ‘‘admitted to’’ fits best. Final Answer if the villagers did not get him admitted in the nearby hospital immediately.

Question 4

English Grammar – Spot the error (identify the erroneous segment or choose ‘‘No error’’). Sentence: Several issues raising in the meeting could be amicably resolved due to his tactful handling.

Accepted Answer

Introduction / Context: Error-spotting questions test command of verb forms and participles. Here, the focus is on the correct non-finite form used to modify a noun (“issues”). Given Data / Assumptions: Noun phrase in question: “Several issues raising”. Event frame: issues occurred in a meeting and were resolved. The rest of the sentence appears structurally sound. Concept / Approach: Past participles are used for completed actions that modify nouns (raised issues). Present participles (-ing) indicate ongoing, active roles (issues that are doing the action), which is not intended here. We need a reduced relative clause equivalent to “issues that were raised”. Step-by-Step Solution: Target meaning: issues were raised during the meeting.Form rule: Use past participle to show passive/complete action modifying a noun.Correction: “Several issues raised in the meeting…” (or “that were raised”).Final corrected sentence: “Several issues raised in the meeting could be amicably resolved due to his tactful handling.” Verification / Alternative check: Substitute the full relative clause: “issues that were raised…”. This clearly matches the context and confirms the past participle “raised” is correct. Why Other Options Are Wrong: “in the meeting could” – correct prepositional placement. “be amicably resolved” – correct passive construction with adverb placement. “due to his tactful handling.” – idiomatic causal phrase; fine. “No error.” – incorrect since option A contains an error. Common Pitfalls: Confusing “-ing” forms (present participle/gerund) with past participles in reduced clauses; overusing “-ing” after nouns when a passive meaning is intended. Final Answer: Several issues raising

Question 5

English Grammar – Spot the error (identify the erroneous segment or choose ‘‘No error’’). Sentence: He deserted the path of honour in order to satisfy his ambition and then went down his doom very quickly.

Accepted Answer

Introduction / Context: This sentence checks idiomatic preposition choice with the fixed expression “go to one’s doom.” Idioms are conventional; altering prepositions causes ungrammatical or non-idiomatic phrasing. Given Data / Assumptions: The intended meaning is that he ultimately met his destruction/fate (“doom”). The phrase given is “went down his doom,” which feels unidiomatic. Concept / Approach: Correct idiom: “go to one’s doom” or “meet one’s doom.” The preposition “to” is required after “go” when indicating movement toward a state/outcome. “Down” is not used in this idiom. Step-by-Step Solution: Identify the idiom: “go to one’s doom.”Spot the error: “went down his doom” uses the wrong preposition and an unidiomatic verb–object pairing.Correction: “and then went to his doom very quickly.” Alternatively: “and then met his doom very quickly.” Verification / Alternative check: Replace with a clearly idiomatic version and read for fluency. “Went to his doom” reads naturally and matches standard English usage. Why Other Options Are Wrong: “He deserted the path of honour” – idiomatic phrase; correct. “in order to” – standard infinitive of purpose; correct. “satisfy his ambition” – correct collocation. “No error.” – incorrect since D is erroneous. Common Pitfalls: Substituting prepositions in fixed expressions; assuming any directional preposition (“down”) will work after “go.” Final Answer: and then went down his doom very quickly.

Question 6

English Grammar – Spot the error (identify the erroneous segment or choose ‘‘No error’’). Sentence: Nitin's nephew, who lives in Bangalore, is eager to travel to Delhi to have a glimpse of the capital.

Accepted Answer

Introduction / Context: This is a relative-clause and preposition placement check. We must verify subject–verb agreement, comma usage with a non-restrictive clause, and natural collocations. Given Data / Assumptions: Non-restrictive clause: “who lives in Bangalore” set off by commas. Main clause: “Nitin’s nephew … is eager to travel to Delhi …”. Object phrase: “a glimpse of the capital.” Concept / Approach: Non-restrictive (non-defining) relative clauses describing a unique noun take commas. “Travel to” requires the preposition “to.” The expression “have a glimpse of” is idiomatic. Step-by-Step Checks: Subject–verb agreement: “nephew … is” – correct.Relative pronoun and punctuation: “who lives …” with commas – correct.Prepositions: “travel to Delhi,” “glimpse of the capital” – correct.Word choice and article usage – natural and idiomatic. Verification / Alternative check: Reading aloud reveals smooth rhythm; replacing with full clause (“who lives in Bangalore”) confirms the comma usage. Why Other Options Are Wrong: Each segment is grammatically accurate, so “No error” is the only correct choice. Common Pitfalls: Mistaking “glimpse of” for “glimpse at” (both occur, but “glimpse of” is idiomatic with a noun object); dropping the comma after a non-restrictive clause. Final Answer: No error.

Question 7

English Grammar – Spot the error (identify the erroneous segment or choose ‘‘No error’’). Sentence: Bible can be regarded as a great.

Accepted Answer

Introduction / Context: This item tests article usage and countability. The phrase “a great” is incomplete without a countable noun (e.g., “a great book/work/scripture”). Given Data / Assumptions: The intended compliment is that the Bible is a great work/book. “Great” here functions as an adjective, not a noun. Concept / Approach: Adjectives require a head noun when used attributively after an article (“a/an/the”). “A great” must be followed by a countable noun; otherwise, the noun phrase is incomplete. Step-by-Step Solution: Locate the incomplete noun phrase: “a great.”Insert the appropriate head noun: “a great book/work/scripture.”Possible corrected versions: “The Bible can be regarded as a great book,” or “The Bible can be regarded as great.” Verification / Alternative check: Remove the article to use predicative adjective: “The Bible can be regarded as great.” This also reads correctly and avoids redundancy. Why Other Options Are Wrong: “Bible” – capitalized proper noun is fine (often preceded by “the,” but as a title it can stand alone in general statements). “can be” – correct modal + be. “regarded as” – correct verb–preposition pairing. “No error.” – incorrect because a head noun is missing after “a great.” Common Pitfalls: Leaving adjectives without head nouns after articles; overcorrecting to “the Bible” is optional stylistically, not the tested error. Final Answer: a great.

Question 8

English Grammar – Spot the error (identify the erroneous segment or choose ‘‘No error’’). Sentence: The institute imparts training in the French.

Accepted Answer

Introduction / Context: This question targets article usage with language names. Standard English uses bare language names (“French,” “Hindi”) without the definite article when referring to the language in general. Given Data / Assumptions: “French” refers to the language, not the people (“the French”) or a specific course. The verb phrase “imparts training in …” is acceptable collocation. Concept / Approach: Drop “the” before language names in generic reference: “in French.” Using “the French” typically refers to people of France, which changes the meaning and becomes incorrect here. Step-by-Step Solution: Identify the mismatched article: “the French.”Correct to bare form: “French.”Revised sentence: “The institute imparts training in French.” Verification / Alternative check: Compare with other language names: “in English,” “in Spanish,” none take an article in this context. Why Other Options Are Wrong: “The institute” – correct subject. “imparts training” – idiomatic for educational settings. “in” – correct preposition. “No error.” – incorrect because option D misuses the article. Common Pitfalls: Confusing “the French” (people) with “French” (language); inserting articles before language names. Final Answer: the French.

Question 9

English Grammar – Spot the error (identify the erroneous segment or choose ‘‘No error’’). Sentence: His father promised to give him anything what he wants if he passes in the examination.

Accepted Answer

Introduction / Context: This item checks relative word choice after “anything” and, secondarily, preposition use with “pass.” The principal error lies in the phrase “anything what,” which is ungrammatical in standard English. Given Data / Assumptions: Indefinite pronoun: “anything.” Subordinate clause indicating desire: “he wants.” Concept / Approach: After “anything,” “that” (or a zero relative) is used, not “what.” Correct constructions are “anything that he wants” or simply “anything he wants.” Step-by-Step Solution: Spot the error: “anything what” – replace “what” with “that” or delete it.Correct version: “give him anything (that) he wants …”.Optional secondary fix: “passes the examination” (omit “in”), though test focus is on the main error. Verification / Alternative check: Read with zero relative: “anything he wants” – natural, widely used. With “that”: equally correct. Why Other Options Are Wrong/Secondary: “His father promised to” – correct starter for an infinitive clause. “wants if he” – tense and pronoun reference are consistent. “passes in the examination.” – Many dialects accept “pass in,” but standard usage prefers “pass the examination.” However, the primary tested error is in option B. “No error.” – incorrect because option B is erroneous. Common Pitfalls: Using “what” after “anything/something/nothing”; over-focusing on minor prepositional variants and missing the central relative error. Final Answer: give him anything what he

Question 10

English Grammar – Spot the error (identify the erroneous segment or choose ‘‘No error’’). Sentence: Being a very fast worker, he is always liking by all his colleagues and superiors too.

Accepted Answer

Introduction / Context: This sentence tests verb form choice in passive constructions. The intended meaning is “he is always liked,” not “liking,” which would express an ongoing action by the subject. Given Data / Assumptions: Participial opener: “Being a very fast worker,” which is fine. Main clause needs a passive form indicating others’ approval of him. Concept / Approach: Passive voice uses the past participle after “be”: “is liked.” The present participle “liking” represents an active, progressive act by the subject, which is illogical here (he does not “like” himself in that sense). Step-by-Step Solution: Locate the verb form: “is always liking” – incorrect.Correct to passive past participle: “is always liked.”Optionally adjust punctuation: combine C and D smoothly – “by all his colleagues and superiors too.” Verification / Alternative check: Rephrase with a relative clause: “who is always liked by …” confirms that the passive is required. Why Other Options Are (mostly) Fine: “Being a very fast worker,” – acceptable non-finite opener. “by all his colleagues … and superiors too.” – prepositional phrase listing approvers; punctuation is stylistic, not grammatical. “No error.” – invalid because B contains a verb-form error. Common Pitfalls: Using “-ing” forms where passive meaning is needed; forgetting that “like” in passive is “liked.” Final Answer: he is always liking

Question 11

English Grammar – Spot the error (identify the erroneous segment or choose ‘‘No error’’). Sentence: While luminaries of the dance world have a dearth of opportunities to display their art, upcoming dancers suffer from an unfortunate lack of exposure.

Accepted Answer

Introduction / Context: Although the content may seem counterintuitive (famous “luminaries” usually have many opportunities), error-spotting focuses on grammar and structure rather than factual truth. We must check conjunction use, parallelism, articles, and prepositions. Given Data / Assumptions: Subordinating conjunction “While …” introduces a contrast. Two grammatically parallel independent ideas are contrasted. Article and preposition usage appear standard. Concept / Approach: “While” may introduce contrast even when both clauses describe scarcity; the contrast can be of type (opportunities vs. exposure), not necessarily direction. Phrases “dearth of opportunities” and “lack of exposure” are idiomatic. The comma after the “While” clause is correctly placed. Step-by-Step Checks: Clause 1: “While … have a dearth of opportunities to display their art” – correct noun phrases, prepositions, and infinitive of purpose.Clause 2: “upcoming dancers suffer from an unfortunate lack of exposure” – correct verb phrase and article use.Punctuation: comma after the dependent clause – correct. Verification / Alternative check: Paraphrase: “Although luminaries have few opportunities, upcoming dancers also lack exposure.” Structure remains sound. Why Other Options Are Wrong: Because no grammatical error exists in A–D, “No error” is the correct choice. Common Pitfalls: Confusing logical plausibility with grammatical correctness; attempting to force “do not have a dearth” based on real-world expectations. Final Answer: No error.

Question 12

English Grammar – Spot the error (identify the erroneous segment or choose ‘‘No error’’). Sentence: I shall be able to complete the work in stipulated time provide you do not disturb me.

Accepted Answer

Introduction / Context: This checks the use of the subordinating conjunction “provided” (meaning “on the condition that”). The noun phrase “stipulated time” is fine; the error is the form “provide” used as a conjunction. Given Data / Assumptions: Intended conditional meaning: ability to finish depends on not being disturbed. Conjunction needed before the condition clause. Concept / Approach: Use “provided” or “provided that,” not “provide,” as the conjunction introducing a condition. Step-by-Step Solution: Identify the conditional connector: “provide” after “stipulated time.”Replace with correct conjunction: “provided (that).”Correct sentence: “I shall be able to complete the work in the stipulated time, provided you do not disturb me.” Verification / Alternative check: Test with synonyms: “so long as,” “on condition that” – confirms the intended conditional relationship. Why Other Options Are Wrong/Acceptable: “I shall be able” – correct future ability construction. “to complete the work in” – correct preposition. “you do not disturb me.” – correct negative present simple for conditional clause. “No error.” – incorrect since C contains the error. Common Pitfalls: Using the verb “provide” where the conjunction “provided” is needed; missing the article before “stipulated time” (optional but preferred: “the stipulated time”). Final Answer: stipulated time provide

Question 13

English Grammar – Spot the error (identify the erroneous segment or choose ‘‘No error’’). Sentence: Our neighbours had repeated the same illogical sequence of activities if we had not brought the facts to their notice.

Accepted Answer

Introduction / Context: This item tests conditional perfect (“third conditional”) structure. When expressing a counterfactual past condition, the main clause requires “would have + past participle,” not simply “had + past participle.” Given Data / Assumptions: Condition introduced by “if”: “if we had not brought …”. Main clause describing unreal past outcome. Concept / Approach: Third conditional pattern: “If + past perfect, would have + past participle.” The sentence incorrectly uses past perfect (“had repeated”) in the main clause instead of “would have repeated.” Step-by-Step Solution: Identify clause types: conditional (if) clause is correct: “if we had not brought …”.Correct the main clause: change “had repeated” to “would have repeated.”Corrected sentence: “Our neighbours would have repeated the same illogical sequence of activities if we had not brought the facts to their notice.” Verification / Alternative check: Swap clause order: “If we had not brought …, our neighbours would have repeated …” – reads naturally and follows the standard structure. Why Other Options Are Wrong/Acceptable: “the same illogical sequence of activities” – grammatically fine noun phrase. “if we had not brought the” – correct start of the conditional clause. “facts to their notice.” – correct prepositional phrase. “No error.” – invalid because option A is erroneous. Common Pitfalls: Using past perfect in both clauses of a third conditional; forgetting the modal “would” (or “could/might”) with “have + past participle” in the main clause. Final Answer: Our neighbours had repeated

Question 14

English grammar – Spot the error (choose the part with an error or “No error”). Sentence: We are happy / to know that / the project completed / strictly as per the schedule.

Accepted Answer

Introduction / Context: This item tests grammar and verb form accuracy in a sentence split into four parts. You must identify the segment containing the grammatical error, or choose “No error” if the sentence is correct. Given Data / Assumptions: The clause refers to a finished action about a project in the past. Standard formal English is required. Each slash-separated chunk represents an option. Concept / Approach: Completed actions typically take a passive construction when the subject receives the action. After “know that,” a full finite clause is expected. The noun “project” cannot perform “completed” without an auxiliary unless it is an adjectival participle, which requires different phrasing. Step-by-Step Solution: Check Part A: “We are happy” — grammatically correct as a predicate adjective.Check Part B: “to know that” — an infinitive of purpose linking to a content clause; correct.Check Part C: “the project completed” — incorrect. It lacks the necessary auxiliary for a passive or perfect form.Preferred corrections: “the project was completed” (simple past passive) or “the project has been completed” (present perfect passive).Check Part D: “strictly as per the schedule.” — idiomatic in Indian English; acceptable. Verification / Alternative check: Substituting “was completed” yields: “We are happy to know that the project was completed strictly as per the schedule,” which is fully grammatical. Why Other Options Are Wrong: A and B are standard; D is idiomatic and acceptable. Only C breaks verb-form rules. Common Pitfalls: Confusing a past participle used adjectivally with a finite verb form; omitting auxiliaries in passive constructions. Final Answer: the project completed

Question 15

English grammar – Spot the error (choose the part with an error or “No error”). Sentence: He was too / irritated to / concentrate on his work / for a long time.

Accepted Answer

Introduction / Context: This question checks idiomatic usage of “too … to” with an infinitive and the correctness of prepositional phrases describing duration. You must locate an error segment or confirm that no error exists. Given Data / Assumptions: The structure “too + adjective + to + verb” expresses an excess preventing the action. “Concentrate on” is the standard preposition collocation. “For a long time” is a standard duration phrase. Concept / Approach: Evaluate each chunk independently: subject–verb agreement, infinitival complement, verb–preposition collocation, and duration phrase. Ensure the meaning is coherent: being too irritated prevents long concentration. Step-by-Step Solution: Part A: “He was too” — correct as the opening of the “too … to” construction.Part B: “irritated to” — correctly provides the adjective followed by the infinitive marker “to.”Part C: “concentrate on his work” — correct verb and collocation (“concentrate on”).Part D: “for a long time.” — standard duration phrase; punctuation acceptable. Verification / Alternative check: Full sentence reads naturally: “He was too irritated to concentrate on his work for a long time.” Synonymous rewrites preserve meaning, confirming correctness. Why Other Options Are Wrong: No segment exhibits a grammatical or idiomatic error; therefore “No error” is the best choice. Common Pitfalls: Misplacing the duration phrase (“for long time” without the article) or changing the collocation to “concentrate at” or “concentrate in,” which would be incorrect. Final Answer: No error.

Question 16

English grammar – Spot the error (choose the part with an error or “No error”). Sentence: The environment in which / companies operating / today is / undergoing frenetic changes.

Accepted Answer

Introduction / Context: This problem checks subject–verb structure inside a relative clause and capitalization. You must identify the erroneous fragment. Given Data / Assumptions: The main subject is “The environment … is undergoing …”. Within the relative phrase “in which …,” a full clause is expected. “Frenetic” is a common adjective and should not be capitalized mid-sentence. Concept / Approach: Inside “in which …,” the phrase “companies operating” is non-finite and needs a finite verb or an auxiliary to complete the clause if it is intended as a clause. The most natural fix is “companies operate” (simple present) or “companies are operating” (present progressive). Step-by-Step Solution: Part A: “The environment in which” — correct start to a relative prepositional phrase.Part B: “companies operating” — incorrect; either “companies operate” or “companies are operating” is required for a complete clause.Part C: “today is” — subject–verb agreement with “environment” is correct.Part D: “undergoing Frenetic changes.” — grammatical but “Frenetic” should be lowercase; however, the primary grammatical error lies in Part B. Verification / Alternative check: Corrected sentence: “The environment in which companies operate today is undergoing frenetic changes.” Reads smoothly. Why Other Options Are Wrong: A and C are correct; D’s capitalization is stylistic, but the grammatical fault is in B, which is the targeted error. Common Pitfalls: Overlooking the need for a finite verb inside relative constructions. Final Answer: companies operating

Question 17

English grammar – Spot the error (choose the part with an error or “No error”). Sentence: He has been undergoing / the special training course / which each of the employees / is required to.

Accepted Answer

Introduction / Context: This question tests complement requirements after verbs like “require.” The sentence is split into parts; pick the segment with the error. Given Data / Assumptions: “Require” followed by “to” must take a bare infinitive verb (e.g., “to attend”). The sentence describes an ongoing course. Concept / Approach: “Is required to” is incomplete without a following verb. It needs an infinitival complement such as “undergo,” “attend,” or “complete.” Step-by-Step Solution: A: “He has been undergoing” — correct present perfect progressive.B: “the special training course” — correct noun phrase.C: “which each of the employees” — correct relative-clause beginning; number agreement okay (“each … is”).D: “is required to.” — erroneous because it lacks the infinitive verb; should be “is required to undergo” or “is required to attend.” Verification / Alternative check: Corrected version: “He has been undergoing the special training course which each of the employees is required to undergo.” Why Other Options Are Wrong: A, B, and C are structurally fine; only D is incomplete. Common Pitfalls: Stopping a “to”-infinitive after “required” without the main verb. Final Answer: is required to.

Question 18

English grammar – Spot the error (choose the part with an error or “No error”). Sentence: A lot of money / is wasted in / the duplication of work / in every organisation.

Accepted Answer

Introduction / Context: This question tests preposition choice with “waste.” Identify the incorrect fragment among the four parts, or mark “No error.” Given Data / Assumptions: Standard collocation in formal English is “waste on” when indicating what the resource is spent on unnecessarily. The rest of the sentence is a general statement about organizations. Concept / Approach: “Waste on” is used for expenditure in terms of time, money, or effort directed toward an unnecessary activity. “Wasted in” would typically refer to being squandered during an activity but is less idiomatic for this construction. Step-by-Step Solution: A: “A lot of money” — correct subject phrase.B: “is wasted in” — preposition is non-idiomatic here; should be “is wasted on.”C: “the duplication of work” — grammatical noun phrase.D: “in every organisation.” — adverbial phrase of frequency/location; acceptable. Verification / Alternative check: Improved sentence: “A lot of money is wasted on the duplication of work in every organisation.” Reads naturally. Why Other Options Are Wrong: A, C, and D are fine; only B contains the idiomatic preposition error. Common Pitfalls: Confusing “waste in” with “waste on”; overusing “in” after passive forms. Final Answer: is wasted in

Question 19

English grammar – Spot the error (choose the part with an error or “No error”). Sentence: We decided not tell to / the patient about / the disease he was / suffering from.

Accepted Answer

Introduction / Context: This item checks infinitive word order and the use of prepositions with reporting verbs. Choose the fragment containing the error. Given Data / Assumptions: The intended structure is “decided not to tell the patient about …”. “Tell” takes a direct object without “to.” Concept / Approach: After “decided,” we use the infinitive “to tell.” The negative marker goes before the “to”-infinitive: “decided not to tell.” We do not say “tell to the patient”; “tell” is ditransitive (“tell someone something”) without “to.” Step-by-Step Solution: Part A as written: “not tell to” — incorrect; should be “not to tell.”Part B: “the patient about” — correct after “tell”: “tell the patient about …”.Part C: “the disease he was” — acceptable lead-in to a relative clause.Part D: “suffering from.” — correct collocation “suffer from.” Verification / Alternative check: Corrected sentence: “We decided not to tell the patient about the disease he was suffering from.” Why Other Options Are Wrong: B, C, and D follow standard usage; only A breaks infinitive order and misuses “to.” Common Pitfalls: Placing “not” after the main verb; adding “to” after “tell.” Final Answer: We decided not tell to

Question 20

English grammar – Spot the error (choose the part with an error or “No error”). Sentence: When I / last see him, / he was / in Calcutta.

Accepted Answer

Introduction / Context: This question examines correct tense usage in a past-time reference. Identify the fragment that violates tense consistency. Given Data / Assumptions: The adverb “last” signals a completed past time. The main event “he was in Calcutta” is in simple past. Concept / Approach: When referring to a specific time in the past, the correct tense for the verb “see” is simple past “saw.” The clause “When I last saw him” sets the time frame for the following past-state clause “he was …”. Step-by-Step Solution: A: “When I” — correct starter to a time clause.B: “last see him,” — incorrect tense; should be “last saw him.”C: “he was” — correct past-tense linking verb.D: “in Calcutta.” — correct prepositional complement of place. Verification / Alternative check: Revised: “When I last saw him, he was in Calcutta.” The sentence is now tense-consistent. Why Other Options Are Wrong: A, C, and D are fine; only B contains the error. Common Pitfalls: Using base form “see” after explicit past-time adverbs; forgetting simple past with “when” clauses. Final Answer: last see him,
