10. Fully Annotated Sentence Walkthroughs

The twelve categories in Section 3 were taught one at a time, in isolation, which is the right way to learn each rule individually — but a real exam sentence never announces which category it belongs to. This section closes that gap by walking through ten complete sentences exactly the way a well-drilled candidate's mind should move through them in the exam hall: reading once for meaning, then running the checklist from Section 2 until something fails or the sentence clears entirely. Read each walkthrough as a demonstration of process, not just of the final answer.

Walkthrough 1

Sentence: (A) The list of shortlisted candidates for the technical post / (B) have been uploaded / (C) on the recruitment portal since this morning. / (D) No error

• First read: a straightforward announcement-style sentence about a list being uploaded.
• Check 1 (subject-verb): the finite verb is "have been uploaded." Its true subject, stripped of the intervening phrase "of shortlisted candidates for the technical post," is "list" — singular. "List...have" fails immediately.
• Verdict: (B). Should be "has been uploaded." No further checks are needed once check 1 fails, per the single-error convention from Section 1.

Walkthrough 2

Sentence: (A) Neither the question paper / (B) nor the answer key / (C) have been released on the official website yet. / (D) No error

• First read: a negative statement about two things not yet being released.
• Check 1: "neither...nor" takes the verb agreeing with the nearer subject, "answer key" (singular). "Have been released" is plural — this fails.
• Verdict: (C). The verb "have been released" sits inside segment (C); it should be "has been released." (This walkthrough is a reminder to check which segment physically contains the failing word before marking your answer — with a correlative pair like "neither...nor," the rule you are checking and the segment carrying the actual verb are not always the same segment.)

Walkthrough 3

Sentence: (A) She has been preparing / (B) for the civil services examination / (C) since the last three years without a single break. / (D) No error

• First read: a personal narrative about ongoing preparation.
• Check 1: subject "she," verb "has been preparing" — singular subject, singular-agreeing present perfect continuous verb. Passes.
• Check 2 (tense): "since the last three years" pairs a duration ("three years") with "since," which should take "for." This fails.
• Verdict: (C). Should be "for the last three years."

Walkthrough 4

Sentence: (A) The coaching institute offers / (B) both weekday batches / (C) as well as weekend batches for working professionals. / (D) No error

• First read: describes two batch options offered by an institute.
• Checks 1–5: subject-verb, tense, pronoun, preposition, and article all pass without incident.
• Check 6 (parallelism/conjunction pairing): "both...as well as" is a broken correlative pair — "both" must pair with "and."
• Verdict: (C). "As well as" sits at the start of this segment; it should be "and weekend batches," correctly pairing with "both."

Walkthrough 5

Sentence: (A) Each of the candidates / (B) must submit their / (C) original documents at the time of verification. / (D) No error

• First read: an instruction about document submission.
• Check 1: "each...must submit" — correctly singular-agreeing modal construction. Passes.
• Check 3 (pronoun): "their," referring back to the singular "each," is flagged under the strict exam convention (see Section 3.3, Example 1) — the formally expected form is "his or her."
• Verdict: (B). Should be "must submit his or her original documents." (Note the caveat from Section 3.3 about this specific pattern's contested status in modern usage — but treat it as the intended answer unless a specific answer key states otherwise.)

Walkthrough 6

Sentence: (A) The syllabus for the mains examination / (B) is far more comprehensive / (C) than the prelims. / (D) No error

• First read: a comparison between two exam stages' syllabi.
• Checks 1–7 pass cleanly.
• Check 8 (comparison): the sentence compares "the syllabus for the mains examination" to "the prelims" — a syllabus compared directly to an exam stage, not to the prelims' syllabus. This is a subtly incomplete comparison.
• Verdict: (C). Should be "than the prelims syllabus" or "than that of the prelims," to compare like with like.

Walkthrough 7

Sentence: (A) Realising that she had left her admit card at home, / (B) a wave of panic / (C) swept over the candidate outside the exam centre gate. / (D) No error

• First read: a dramatic, narrative-style sentence about forgetting an admit card.
• Checks 1–8 pass.
• Check 9 (modifier placement): the opening participial phrase "Realising that she had left her admit card at home" logically describes a person, but the subject immediately following it is "a wave of panic," which cannot realise anything. This is a classic dangling modifier.
• Verdict: (B). The sentence needs restructuring so "the candidate," not "a wave of panic," is the subject following the opening phrase — e.g., "...the candidate felt a wave of panic sweep over her."

Walkthrough 8

Sentence: (A) The number of women appearing / (B) for competitive exams / (C) has risen steadily over the past decade. / (D) No error

• First read: a statistical observation about a rising trend.
• Check 1: "the number...has risen" — correctly singular. Passes.
• Checks 2 through 9: tense ("has risen...over the past decade" is a correctly formed present-perfect-with-duration pairing), prepositions, articles, parallelism, redundancy, comparison, and modifier placement all pass on inspection.
• Verdict: (D) — No error. This sentence is included specifically to demonstrate that a clean run through all nine checks, with nothing failing, is itself a confident, positive conclusion — not a sign you missed something.

Walkthrough 9

Sentence: (A) The invigilator distributed the OMR sheets / (B) to the students with a stern warning / (C) about malpractice before the exam began. / (D) No error

• First read: describes an invigilator handing out answer sheets along with a warning.
• Checks 1–8 pass.
• Check 9 (modifier placement): "with a stern warning about malpractice" sits directly after "the students," making it briefly ambiguous whether the warning belongs to the students or to the act of distribution — but on a careful second look, this phrase is naturally read as modifying the entire act of distributing ("distributed...with a warning"), which is a standard, unambiguous adverbial-phrase attachment, not a genuine misplaced modifier like Walkthrough 7's dangling opener.
• Verdict: (D) — No error. This walkthrough exists to sharpen the distinction between a genuine misplaced modifier (Section 3.10, Examples 3–4) and a phrase that merely sits near two possible nouns but is not actually ambiguous once read as a whole — over-flagging such phrases is a common false-positive error among over-cautious candidates.

Walkthrough 10

Sentence: (A) One of the major reasons behind the low pass percentage / (B) are the unexpectedly / (C) high difficulty level of the quantitative section. / (D) No error

• First read: an explanatory sentence about a poor pass rate.
• Check 1: "one of the major reasons...are" — the true subject is "one," singular, so the verb should be "is," not "are." This fails immediately.
• Verdict: (B). Should be "is the unexpectedly high difficulty level." This is the classic "one of the + plural noun" trap from trap catalogue entry 4, now seen fully worked inside the checklist process rather than as an isolated one-line rule.
