Answer Key with Explanations

Part A

1. (C) — "number...have crossed" should be "has crossed"; "number" is the singular subject.
2. (C) — "since ten years" should be "for ten years"; "since" pairs with a point in time, not a duration.
3. (B) — "Each...were given" should be "was given"; "each" is always singular.
4. (C) — "neither...nor" takes the verb agreeing with the nearer subject, "marks" (plural), so it should be "were uploaded," not "was uploaded."
5. (D) No error — "congratulated...on" is the correct collocation.
6. (D) No error — "an efficient" correctly uses "an" before a vowel sound.
7. (C) — "to be revising" breaks parallelism with "to practise"; should be "and to revise notes daily."
8. (A) — "revert back" is redundant; should be simply "revert."
9. (C) — only two finalists are being compared ("the two shortlisted candidates"), so the comparative "better" is required, not the superlative "the best."
10. (B) — "neither...or" should be "neither...nor."
11. (B) — dangling modifier; "the exam centre" cannot miss a bus — should be restructured with a logical subject, e.g., "he found the exam centre impossibly far."
12. (B) — "less candidates" should be "fewer candidates."
13. (B) — "illicit" should be "elicit."
14. (C) — "challenges...are adapting" — the true subject is "one of the biggest challenges," singular in its head noun "challenge"; should be "is adapting."
15. (B) — "already accepted" should be "had already accepted" (past perfect for the earlier of two past actions).
16. (D) No error — correctly uses "his or her" with the singular "every candidate."
17. (A) — "Rohit and I" as the object of "asked" should be "Rohit and me."

22. (A) — "The most candidates" should simply be "Most candidates" (no article before a general plural statement).
23. (B) — "a large amount of complaints" should be "a large number of," since "complaints" is countable.
24. (B) — "but also improving" should be "but also to improve," matching the infinitive "to reduce."
25. (C) — "who is remaining fair" should be "and remains fair," matching "listens" and "responds."
26. (D) No error — "revert" alone (without "back") is correctly used here.
27. (A) — "final outcome" is redundant; should be simply "outcome."
28. (A) — "each and every" is redundant; should be "each" or "every," not both.
29. (B) — "past history" is redundant; should be simply "history."
30. (C) — the "as good...as" frame is broken; should be "was as good as, if not better than, her actual score."
31. (B) — only two candidates compared, so "the best" should be "better."
32. (B) — "more higher" is a double comparative; should be simply "higher."
33. (C) — "any exam" should be "any other exam" to avoid comparing the syllabus to a set that includes itself.
34. (B) — "neither...or" should be "neither...nor."
35. (C) — "deputy superintendents" (plural, nearer subject) requires "are," not "is."
36. (B) — "both...as well as" is a broken pair; should be "both the answer key and the response sheet."
37. (B) — "whether...and" should be "whether...or."
38. (B) — dangling modifier; "the revision schedule" did not complete the syllabus — should be restructured, e.g., "she found the revision schedule far less stressful."
39. (A) — misplaced "only"; should be "checked only the admit cards," to correctly limit what was checked rather than suggesting checking was the sole action performed.
40. (B) — dangling modifier; "a sudden gust of wind" cannot walk — should be restructured with the candidate as the logical subject of "walking."
41. (B) — misplaced modifier; "with a query mark on the cover page" should sit next to "answer booklet," not appear to describe "the student."
42. (B) — dangling modifier; "the online form" cannot realise anything — should be restructured with "the applicant" as the logical subject.
43. (D) No error — "fewer" correctly modifies the countable "chairs."

47. (D) No error — "not only...but also" correctly paired with parallel verb phrases.
48. (B) — "each...carry" should be "carries"; "each" is singular.
49. (B) — "were present" should be "was present"; "along with two invigilators" is parenthetical and does not pluralise the subject "centre superintendent."
50. (D) No error — the opening participial phrase correctly attaches to "the officer."
51. (B) — "informed about" without an object should be "informed the staff/candidates about," since "inform" in formal register expects a direct object.
52. (A) — "two years ago since" is a redundant double time-marker; should be either "It is two years since he joined" or "He joined two years ago."
53. (D) No error — "wait for" is correctly used here.
54. (A) — "hasn't hardly" is a double negative; should be "has hardly slept."
55. (B) — "both...to each other" is redundant with "alike," which already implies mutual comparison; "to each other" should be dropped.
56. (A) — fronted "Never" requires subject-auxiliary inversion: should be "Never did he attend."
57. (C) — "the latter candidate," referring to the second of two previously mentioned candidates, is misused where no such pair was established; likely intended word is simply "the other candidate" — flag as a confusable-pair error on "latter."
58. (B) — "stationary" (not moving) should be "stationery" (writing materials).
59. (B) — "informations" is an incorrect plural of the uncountable noun "information."
60. (D) No error — "except" (excluding) and "accept" (to agree to) are each correctly used in their respective roles; this is a deliberate trap testing whether candidates over-flag this confusable pair out of reflex.
61. (B) — "the reason...is because" is redundant; should be "is that."
62. (D) No error — "only" correctly precedes and limits "the shortlisted candidates."

65. (D) No error — "comply with" is correctly used.
66. (D) No error — "arrived at the exam centre" correctly uses "at" for a specific venue.
67. (D) No error — sentence is grammatically clean throughout.
68. (C) — "instructions...needs" should be "need"; the plural subject "instructions" is unaffected by the intervening phrase.
69. (D) No error — "for the last eight years" correctly pairs with the present perfect continuous.
70. (D) No error — "begins," a scheduled timetable event, is correctly kept in the present tense despite the past-tense reporting verb.
71. (C) — "the power...goes off" should be "went off," matching the past continuous narrative "was solving...when."
72. (C) — "will be preponed" should be "would be preponed," shifted back under the past-tense reporting verb "informed."
73. (D) No error — "who" correctly functions as the subject of the embedded clause.
74. (D) No error — "each...her" correctly agrees in number and gender.
75. (D) No error — "prohibit...from" and "appearing for" are both correctly used.
76. (B) — "different than" should be "different from."
77. (D) No error — the relative clause is correctly placed and punctuated.
78. (D) No error — "a large number of candidates" correctly quantifies the countable noun.
79. (C) — "neither...nor...have changed" — the nearer subject "marking scheme" is singular, so it should be "has changed."
80. (D) No error — "who," referring to the plural "few candidates," correctly takes "have cleared."
81. (D) No error — correctly formed third conditional.
82. (C) — "complimentary gift" is redundant; should be simply "complimentary offer" or "free gift," not both stacked.
83. (A) — "a large amount of candidates" should be "a large number of," since "candidates" is countable.
84. (C) — pronoun-antecedent mismatch: "it" should be "them," agreeing in number with the plural "the documents."
85. (B) — missing article before a superlative: "highest marks" should be "the highest marks."
86. (D) No error — "in spite of," written correctly as separate words, is used correctly here.
87. (B) — "precede" should be "proceed."
88. (A) — "Myself and my colleague" as a subject should be "My colleague and I."
89. (D) No error — "the list...is displayed" correctly keeps the singular verb, unaffected by the intervening "of shortlisted candidates."
90. (B) — "and because she managed her time well" breaks parallelism with the preceding nouns "discipline" and "dedication"; should be a matching noun phrase, e.g., "and time management."

Part B

1. (b) — "fewer seats" correctly matches the countable noun "seats."
2. (b) — "One of the reasons...is" correctly gives the verb agreeing with "one," not the plural "reasons."
3. (a) — "neither...nor" correctly paired, with the verb "was" agreeing with the nearer singular subject "staff" (treated as a unit).
4. (a) — "affect," the verb, is correctly used to mean "to influence."
5. (b) — "he found the hall" gives the opening participial phrase a correct, logical subject.
6. (b) — "any other syllabus" makes the comparison logically complete.
7. (b) — "revert" alone, without the redundant "back," is correct.
8. (d) — correctly distinguishes "stationery" (writing materials, in the first half) from "stationary" (not moving, in the second half).
9. (b) — "The list...is displayed" correctly keeps the verb agreeing with the singular head noun "list."
10. (b) — "Never did he attend" correctly applies subject-auxiliary inversion after the fronted negative adverb "Never."
