Subject-Verb Agreement: Collective Nouns Quiz | Advanced Level | 30 Questions & Answers with Explanations

30 questions

This advanced-level quiz tests Collective Nouns & A Number Of vs The Number Of through complex, formally worded sentences and error-spotting formats that mirror the mains-level difficulty of SSC CGL, IBPS PO, Railways, Bank Clerk, and State PSC papers. At this level, three key concepts are tested: correctly applying the collective-noun singular rule even when buried inside long, multi-clause sentences with several genuine plural distractors, confidently distinguishing "a number of" from "the number of" when both appear in the same sentence or when separated from the verb by extensive description, and recognising when a collective noun's default singular treatment can shift to plural based on explicit contextual signals (individual member emphasis). Before you attempt this quiz, read through the Subject-Verb Agreement — it'll make these questions much easier to crack. At the advanced stage, the underlying rules stay exactly as they were at the beginner level — only the sentence architecture and the subtlety of the contextual signals become more demanding.

Q1

Spot the error: "The committee tasked with reviewing the proposed amendments to the constitution have submitted its final report to the assembly."

View solution & Explanation

Correct Answer the proposed amendments to the constitution have submitted

"Committee" is a collective noun acting as one unit here (reinforced by "its" later in the sentence, confirming singular treatment), so it takes a singular verb — "have submitted" is incorrect; it should be "has submitted."

Correct sentence: "The committee tasked with reviewing the proposed amendments to the constitution has submitted its final report to the assembly."

Memory hook: notice the sentence correctly uses "its" (singular possessive) later on — this internal clue confirms the committee is being treated as one unit, so the earlier verb should match with "has," not "have."

Q2

Fill in the blank: "A number of the amendments proposed by opposition members during the marathon debate session ___ ultimately incorporated into the final version of the bill."

View solution & Explanation

Correct Answer were

"A number of" means "many," so it takes a plural verb, regardless of the lengthy descriptive phrase "proposed by opposition members during the marathon debate session" that separates it from the verb.

Correct sentence: "A number of the amendments proposed by opposition members during the marathon debate session were ultimately incorporated into the final version of the bill."

Memory hook: no matter how long the distance between "a number of" and the verb becomes, the substitution test ("many amendments were incorporated") still confirms the plural verb instantly.

Q3

Spot the error: "The staff of the embassy, all of whom had received extensive security training, was evacuated safely before the situation escalated further."

View solution & Explanation

Correct Answer was evacuated safely

"Staff" here is clearly emphasising the individual members acting/being treated separately (strongly reinforced by "all of whom," which explicitly refers to each individual person), so it should take a plural verb — "was evacuated" is incorrect; it should be "were evacuated."

Correct sentence: "The staff of the embassy, all of whom had received extensive security training, were evacuated safely before the situation escalated further."

Memory hook: "all of whom" is an even stronger individual-member signal than "their" — whenever a relative clause explicitly refers to "each" or "all" of a collective noun's members individually, expect the plural treatment.

Q4

Fill in the blank: "The number of casualties reported in the immediate aftermath of the disaster ___ later revised downward once accurate records became available."

View solution & Explanation

Correct Answer was

"The number of" refers to a specific count, so it takes a singular verb, regardless of the plural noun "casualties" and the substantial descriptive material that follows.

Correct sentence: "The number of casualties reported in the immediate aftermath of the disaster was later revised downward once accurate records became available."

Memory hook: this reinforces the pattern in a sombre, news-style context — "casualties," though genuinely plural and emotionally weighty, is still not the true subject; "the number" alone governs the verb.

Q5

Spot the error: "The government, along with several international agencies coordinating the relief effort, have pledged substantial funding for reconstruction."

View solution & Explanation

Correct Answer have pledged substantial funding

"The government" is the true subject (a collective noun acting as one unit), and "along with several international agencies coordinating the relief effort" is a parenthetical phrase (combining the collective-noun rule with the parenthetical-phrase rule), so the verb agrees only with "the government" — "have pledged" is incorrect; it should be "has pledged."

Correct sentence: "The government, along with several international agencies coordinating the relief effort, has pledged substantial funding for reconstruction."

Memory hook: this combines two rules from different topics once more — the collective-noun singular rule AND the "along with" parenthetical rule — both independently confirming the same singular verb.

Q6

Fill in the blank: "A number of the recommendations contained in the auditor's report, particularly those relating to internal controls, ___ still awaiting formal board approval."

View solution & Explanation

Correct Answer are

"A number of" means "many," so it takes a plural verb, regardless of the interrupting phrase "particularly those relating to internal controls" placed between the subject and the verb.

Correct sentence: "A number of the recommendations contained in the auditor's report, particularly those relating to internal controls, are still awaiting formal board approval."

Memory hook: a comma-set-off interrupting phrase doesn't change the underlying "many = plural" logic of "a number of" — mentally remove it and check the core structure directly.

Q7

Spot the error: "The jury, having spent nearly two full days weighing the evidence presented by both sides, were finally ready to deliver its verdict."

View solution & Explanation

Correct Answer were finally ready to deliver

"Jury" is a collective noun acting as one unit here (confirmed by "its verdict" later in the sentence, a singular possessive), so it takes a singular verb — "were finally ready" is incorrect; it should be "was finally ready."

Correct sentence: "The jury, having spent nearly two full days weighing the evidence presented by both sides, was finally ready to deliver its verdict."

Memory hook: as with the committee example earlier, check for a singular possessive pronoun ("its") later in the sentence — it's a strong internal confirmation of how the collective noun is meant to be treated throughout.

Q8

Fill in the blank: "The number of students enrolling in STEM programmes at universities across the country, despite a general decline in overall higher education enrolment, ___ continued to rise steadily."

View solution & Explanation

Correct Answer has

"The number of" refers to a specific count, so it takes a singular verb, regardless of the plural noun "students" and the extensive contrasting clause that follows.

Correct sentence: "The number of students enrolling in STEM programmes at universities across the country, despite a general decline in overall higher education enrolment, has continued to rise steadily."

Memory hook: this is one of the longest distractor chains tested for this rule — no matter how much contrasting or qualifying detail is added, "the number" alone remains the singular subject throughout.

Q9

Spot the error: "The panel of experts convened specifically to investigate the allegations have concluded that no wrongdoing occurred."

View solution & Explanation

Correct Answer have concluded that no wrongdoing occurred

"Panel" is a collective noun acting as one unit (a body reaching one collective conclusion), so it takes a singular verb — "have concluded" is incorrect; it should be "has concluded."

Correct sentence: "The panel of experts convened specifically to investigate the allegations has concluded that no wrongdoing occurred."

Memory hook: "experts" (plural, inside the prepositional phrase "of experts") is a tempting distractor, but "panel" itself, acting as one unified investigative body reaching a single conclusion, remains singular.

Q10

Fill in the blank: "A number of the witnesses called to testify before the commission, several of whom had initially refused to cooperate, ___ eventually provided detailed statements."

View solution & Explanation

Correct Answer have

"A number of" means "many," so it takes a plural verb, regardless of the interrupting clause "several of whom had initially refused to cooperate" placed between the subject and the verb.

Correct sentence: "A number of the witnesses called to testify before the commission, several of whom had initially refused to cooperate, have eventually provided detailed statements."

Memory hook: this sentence is packed with plural signals throughout (witnesses, several) that all point the same direction as the core "a number of = many" rule — a rare case where every clue agrees rather than conflicts.

Q11

Spot the error: "The crew, several of whom had served together on previous voyages, was confident in their ability to handle the unexpected mechanical failure."

View solution & Explanation

Correct Answer was confident in their ability

"Crew" here is clearly being treated with individual-member emphasis (strongly signalled by "several of whom" and "their ability," both referring to the crew members individually), so it should take a plural verb — "was confident" is incorrect; it should be "were confident."

Correct sentence: "The crew, several of whom had served together on previous voyages, were confident in their ability to handle the unexpected mechanical failure."

Memory hook: "several of whom" combined with "their" is a doubled individual-member signal — when a sentence uses both types of clue together, the plural reading becomes very strongly indicated.

Q12

Fill in the blank: "The number of applications received for the newly created position, submitted within just the first forty-eight hours of the posting, ___ far exceeded initial expectations."

View solution & Explanation

Correct Answer has

"The number of" refers to a specific count, so it takes a singular verb, regardless of the plural noun "applications" and the participial phrase that follows.

Correct sentence: "The number of applications received for the newly created position, submitted within just the first forty-eight hours of the posting, has far exceeded initial expectations."

Memory hook: this reinforces the pattern once more in an HR/recruitment context — "applications," though genuinely plural, is never the true subject when preceded by "the number of."

Q13

Spot the error: "The board of trustees, several members of which have served for over a decade, are set to vote on the proposed merger next month."

View solution & Explanation

Correct Answer are set to vote on the proposed merge

"Board" is a collective noun acting as one unit here (voting as a single body on one decision), so it takes a singular verb — "are set to vote" is incorrect; it should be "is set to vote."

Correct sentence: "The board of trustees, several members of which have served for over a decade, is set to vote on the proposed merger next month."

Memory hook: notice this sentence contains "have served" (correctly plural, referring to individual "members" within the relative clause) right next to the error — don't let a correctly plural verb inside a relative clause convince you the MAIN verb should also be plural; check each clause's own subject separately.

Q14

Spot the error: "The audience, visibly restless after the third delay in as many hours, was beginning to voice its frustration through scattered heckling."

View solution & Explanation

Correct Answer No error

This sentence is correct — "audience" here is treated as one unified collective body (confirmed by "its frustration," a singular possessive), correctly taking the singular verb "was," following standard Indian competitive exam convention for collective nouns acting as a unit.

Correct sentence stands as written.

Memory hook: "its" (singular) here confirms the intended singular treatment, contrasting with the "their" and "all of whom" signals that shifted "staff" and "crew" to plural in earlier questions — always check which possessive pronoun the sentence actually uses.

Q15

Fill in the blank: "The number of endangered species recorded in this particular ecosystem, a figure that has risen alarmingly over the past two decades, ___ a matter of serious concern for conservationists worldwide."

View solution & Explanation

Correct Answer is

"The number of" refers to a specific count, so it takes a singular verb, reinforced by the appositive phrase "a figure that has risen alarmingly," which explicitly restates "the number" as a single figure/statistic.

Correct sentence: "The number of endangered species recorded in this particular ecosystem, a figure that has risen alarmingly over the past two decades, is a matter of serious concern for conservationists worldwide."

Memory hook: the appositive phrase here ("a figure that...") is a strong internal clue reinforcing that "the number" is indeed being treated as one singular statistic, not a plural count of species.

Q16

Spot the error: "The government's negotiating team, comprising senior officials from three separate ministries, were unanimous in its recommendation to proceed with the trade agreement."

View solution & Explanation

Correct Answer were unanimous in its recommendation

"Team" is a collective noun acting as one unit (confirmed by "its recommendation," a singular possessive, appearing in the very same clause), so it takes a singular verb — "were unanimous" is incorrect; it should be "was unanimous."

Correct sentence: "The government's negotiating team, comprising senior officials from three separate ministries, was unanimous in its recommendation to proceed with the trade agreement."

Memory hook: this sentence contains an internal contradiction worth noticing — "were" (plural) directly followed by "its" (singular) within the same clause; when you spot mismatched signals like this, the fix is always to make the verb match the confirmed possessive pronoun.

Q17

Fill in the blank: "A number of the safeguards built into the original legislation, according to legal experts who reviewed the draft extensively, ___ since been quietly removed during subsequent amendments."

View solution & Explanation

Correct Answer have

"A number of" means "many," so it takes a plural verb, regardless of the interrupting phrase "according to legal experts who reviewed the draft extensively" placed between the subject and the verb.

Correct sentence: "A number of the safeguards built into the original legislation, according to legal experts who reviewed the draft extensively, have since been quietly removed during subsequent amendments."

Memory hook: this reinforces the pattern in a dense, legal-sounding sentence — regardless of how much attribution or qualifying language ("according to legal experts...") separates the subject from the verb, "a number of" still means "many" and still takes a plural verb.

Q18

Spot the error: "The army, mobilised swiftly in response to the natural disaster, was praised widely for the speed and efficiency of their relief operations."

View solution & Explanation

Correct Answer of their relief operations

This sentence contains an internal inconsistency: "was" (correctly singular, treating "army" as one unit) is followed later by "their" (a plural possessive), which contradicts the singular treatment established earlier — the correct, consistent form should use "its," not "their."

Correct sentence: "The army, mobilised swiftly in response to the natural disaster, was praised widely for the speed and efficiency of its relief operations."

Memory hook: this reverses the pattern from earlier questions — instead of an incorrect verb, the error here is a pronoun (their) that doesn't match the correctly singular verb (was) established earlier in the same sentence; consistency across the whole sentence matters, not just the subject-verb pair itself.

Q19

Fill in the blank: "The number of formal complaints lodged against the department over the course of the fiscal year, when compared against figures from previous years, ___ notably lower than officials had anticipated."

View solution & Explanation

Correct Answer is

"The number of" refers to a specific count, so it takes a singular verb, regardless of the plural noun "complaints" and the comparative clause "when compared against figures from previous years" that follows.

Correct sentence: "The number of formal complaints lodged against the department over the course of the fiscal year, when compared against figures from previous years, is notably lower than officials had anticipated."

Memory hook: notice "figures" (plural) appears within the comparative clause itself — yet another distractor layered into an already-long sentence, but "the number" at the very start remains the sole determinant of the verb throughout.

Q20

Spot the error: "The panel, deeply divided on several key questions throughout the proceedings, was ultimately unable to reach consensus among its own members."

View solution & Explanation

Correct Answer No error

This sentence is correct — "panel" is treated as one collective unit (confirmed by "its own members," a singular possessive), correctly taking the singular verb "was," even though the sentence describes internal disagreement among the panel's individual members.

Correct sentence stands as written.

Memory hook: a panel can be internally "divided" in meaning while still being grammatically treated as one singular unit — the content of the sentence (disagreement) doesn't automatically override the grammatical convention (collective noun = singular) unless the pronoun itself shifts to plural.

Q21

Fill in the blank: "A number of the internal memos circulated among senior management during the crisis, later obtained through a formal records request, ___ revealed a starkly different version of events."

View solution & Explanation

Correct Answer have

"A number of" means "many," so it takes a plural verb, regardless of the participial phrase "later obtained through a formal records request" that separates it from the verb.

Correct sentence: "A number of the internal memos circulated among senior management during the crisis, later obtained through a formal records request, have revealed a starkly different version of events."

Memory hook: as a near-final reinforcement — no matter how investigative or journalistic the surrounding sentence sounds, the core "a number of = many = plural" substitution test remains completely reliable.

Q22

Spot the error: "The committee's staff, many of whom had worked on the project since its inception, was reassigned following the sudden budget cuts."

View solution & Explanation

Correct Answer was reassigned following the sudden budget cuts

"Staff" here is clearly being treated with individual-member emphasis (strongly signalled by "many of whom," referring to the individual people), so it should take a plural verb — "was reassigned" is incorrect; it should be "were reassigned."

Correct sentence: "The committee's staff, many of whom had worked on the project since its inception, were reassigned following the sudden budget cuts."

Memory hook: "many of whom," like "several of whom" and "all of whom," is a reliable individual-member signal for "staff" — whenever you see this construction, expect the plural treatment.

Q23

Fill in the blank: "The number of shareholders voting in favour of the proposed restructuring, based on the preliminary count released this morning, ___ sufficient to secure approval."

View solution & Explanation

Correct Answer is

"The number of" refers to a specific count, so it takes a singular verb, regardless of the plural noun "shareholders" and the participial phrase "based on the preliminary count released this morning" that follows.

Correct sentence: "The number of shareholders voting in favour of the proposed restructuring, based on the preliminary count released this morning, is sufficient to secure approval."

Memory hook: notice "count" appears within the distractor phrase itself, echoing the meaning of "the number" — but grammatically, only the actual subject "the number" at the sentence's start determines the verb.

Q24

Spot the error: "The government, in consultation with a number of independent economic advisors brought in specifically for this review, have decided to postpone the policy's implementation."

View solution & Explanation

Correct Answer have decided to postpone

"The government" is the true subject (a collective noun acting as one unit), and "in consultation with a number of independent economic advisors..." is a parenthetical phrase (note that "a number of" appears WITHIN this distractor phrase, not as the main subject), so the verb agrees only with "the government" — "have decided" is incorrect; it should be "has decided."

Correct sentence: "The government, in consultation with a number of independent economic advisors brought in specifically for this review, has decided to postpone the policy's implementation."

Memory hook: this is a sophisticated trap — "a number of" normally signals a plural verb, but here it's buried inside a parenthetical phrase describing who was consulted, not functioning as the sentence's actual subject; always identify the TRUE subject first before applying any specific-phrase rule.

Q25

Fill in the blank: "The crew assigned to the mission, each member of which underwent months of specialised training, ___ fully prepared for every contingency."

View solution & Explanation

Correct Answer were

"Crew" here is clearly being treated with individual-member emphasis (strongly signalled by "each member of which," explicitly referring to individual crew members), so it should take a plural verb.

Correct sentence: "The crew assigned to the mission, each member of which underwent months of specialised training, were fully prepared for every contingency."

Memory hook: "each member of which" functions the same way as "all of whom" and "several of whom" — any relative clause that explicitly breaks the collective noun down into its individual members signals the plural treatment.

Q26

Spot the error: "The number of votes cast in favour of the resolution, though technically sufficient to meet the quorum requirement, were narrower than the sponsors had hoped."

View solution & Explanation

Correct Answer were narrower than the sponsors had hoped

"The number of" refers to a specific count, so it takes a singular verb — "were narrower" is incorrect; it should be "was narrower."

Correct sentence: "The number of votes cast in favour of the resolution, though technically sufficient to meet the quorum requirement, was narrower than the sponsors had hoped."

Memory hook: "votes" (plural, right after "the number of") and the concessive clause "though technically sufficient..." are both distractors — "the number" alone, as always, determines the singular verb.

Q27

Fill in the blank: "A number of the case studies presented at the conference, several of which challenged long-held assumptions in the field, ___ generated considerable debate among attendees."

View solution & Explanation

Correct Answer have

"A number of" means "many," so it takes a plural verb, regardless of the interrupting clause "several of which challenged long-held assumptions in the field" placed between the subject and the verb.

Correct sentence: "A number of the case studies presented at the conference, several of which challenged long-held assumptions in the field, have generated considerable debate among attendees."

Memory hook: notice "several," which independently signals plurality, appears twice in this sentence's logic — once explicitly in the interrupting clause, and once implicitly through "a number of" itself — both reinforcing the same plural conclusion.

Q28

Fill in the blank: "A number of the safety violations identified during the inspection, though relatively minor when considered individually, ___ collectively significant enough to warrant a formal warning."

View solution & Explanation

Correct Answer are

"A number of" means "many," so it takes a plural verb, regardless of the concessive clause "though relatively minor when considered individually" placed between the subject and the verb.

Correct sentence: "A number of the safety violations identified during the inspection, though relatively minor when considered individually, are collectively significant enough to warrant a formal warning."

Memory hook: notice the interrupting clause actually discusses "individually" versus "collectively" — this is about the meaning of the sentence's content, not a grammatical signal; the underlying "a number of = many = plural" rule is unaffected by this thematic detail.

Q29

Spot the error: "The board, despite considerable internal disagreement over the company's long-term direction, was ultimately united in their decision to proceed cautiously."

View solution & Explanation

Correct Answer was ultimately united in their decision

This sentence contains an internal inconsistency: "was" (correctly singular, treating "board" as one unit) is followed by "their" (a plural possessive), which contradicts the singular treatment — the correct, consistent form should use "its," not "their."

Correct sentence: "The board, despite considerable internal disagreement over the company's long-term direction, was ultimately united in its decision to proceed cautiously."

Memory hook: this reinforces the earlier "army...their" pattern — when a sentence has already committed to a singular verb for a collective noun, any pronoun referring back to it later in the sentence must also stay singular ("its"), not shift to plural ("their").

Q30

 Fill in the blank: "The number of independent studies confirming the treatment's effectiveness, though still relatively small compared to the total body of research on the subject, ___ growing steadily each year."

View solution & Explanation

Correct Answer is

"The number of" refers to a specific count, so it takes a singular verb, regardless of the plural noun "studies" and the extensive concessive clause that follows.

Correct sentence: "The number of independent studies confirming the treatment's effectiveness, though still relatively small compared to the total body of research on the subject, is growing steadily each year."

Memory hook: as a final, comprehensive reinforcement across this entire topic — whether the sentence is short and simple or long and layered with concessive clauses, comparative phrases, and multiple plural distractors, "the number of" always, without exception, takes a singular verb, while "a number of" always takes a plural one; this single pair remains one of the most reliable, trap-proof rules in the whole SVA system once fully internalised.
