Subject-Verb Agreement: And / As Well As / Along With Quiz | Advanced Level | 30 Questions & Answers with Explanations

"Along with two senior officials from the ministry" is a parenthetical phrase, so the verb should agree only with "the finance secretary" (singular) — "were summoned" is incorrect; it should be "was summoned."

Correct sentence: "The finance secretary, along with two senior officials from the ministry, was summoned to appear before the parliamentary committee next week."

Memory hook: no matter how official or bureaucratic the sentence sounds, a parenthetical phrase full of plural officials still never changes the singular subject's verb.

"Together with the board members and the company's legal counsel" is a parenthetical phrase (even with its own internal and), so the verb agrees only with "the chairman" (singular).

Correct sentence: "The chairman, together with the board members and the company's legal counsel, is scheduled to meet the regulators on Thursday."

Memory hook: an "and" appearing INSIDE a parenthetical phrase doesn't turn the whole phrase into a compound subject — the parenthetical connector at the start ("together with") still governs, keeping the true subject singular.

"The novelist and her longtime editor" are joined by and, forming a genuine compound, plural subject (the intervening relative clause "who has worked with her since her debut" is a distractor describing the editor, not a parenthetical connector) — "was interviewed" is incorrect; it should be "were interviewed."

Correct sentence: "The novelist and her longtime editor, who has worked with her since her debut, were interviewed together about their creative partnership."

Memory hook: don't confuse a relative clause embedded within a compound subject for a parenthetical phrase — "and" still creates a plural subject even when a "who" clause interrupts partway through.

"Besides several cabinet colleagues and senior bureaucrats" is a parenthetical phrase, so the verb agrees only with "the prime minister" (singular), regardless of how many plural nouns are packed inside the phrase.

Correct sentence: "The prime minister, besides several cabinet colleagues and senior bureaucrats, is expected to attend the summit in person."

Memory hook: no matter how many plural nouns are stacked inside a parenthetical phrase, the rule never changes — trace back to the true subject before the phrase begins.

"Trial and error" is a fixed-pair concept taking a singular verb, and "rather than rigid adherence to theory" functions as a parenthetical/contrasting phrase (similar to "as well as"), not a compound-subject connector, so "remain" is incorrect; it should be "remains."

Correct sentence: "Trial and error, rather than rigid adherence to theory, remains the most reliable method for early-stage scientific discovery."

Memory hook: "rather than" joins the parenthetical family in function (it doesn't create a compound subject) — combined with the fixed-pair "trial and error," this sentence needs a singular verb for two independent reasons.

"The architect and the structural engineer" are joined by and, forming a genuine compound, plural subject.

Correct sentence: "The architect and the structural engineer have collaborated closely throughout the design phase of the bridge."

Memory hook: this is a straightforward compound-subject case included to confirm you can still recognise the basic and rule even amid a run of trickier parenthetical questions.

"Law and order" is a fixed-pair concept, taking a singular verb, regardless of the substantial descriptive clause "historically a defining priority for any functioning state" placed between the subject and the verb.

Correct sentence: "Law and order, historically a defining priority for any functioning state, is once again at the centre of the political debate."

Memory hook: a long appositive phrase set off by commas doesn't change a fixed pair's singular status — mentally remove the interrupting phrase and check the core subject-verb pair directly.

"The witness and the defendant's own legal team" are joined by and, forming a genuine compound, plural subject (the phrase "despite representing opposing sides" is a distractor, not a parenthetical connector) — "was seen" is incorrect; it should be "were seen."

Correct sentence: "The witness and the defendant's own legal team, despite representing opposing sides, were seen exchanging a brief, cordial greeting outside the courtroom."

Memory hook: "despite," like "who," "which," and "rather than" in some of the earlier questions, introduces descriptive or contrasting information — but it does NOT function as a parenthetical connector like "along with"; the and earlier in the sentence still governs, making the subject plural.

"Along with the deans of every faculty and several senior professors" is a parenthetical phrase, so the verb agrees only with "the vice-chancellor" (singular), no matter how many plural nouns are stacked inside it.

Correct sentence: "The vice-chancellor, along with the deans of every faculty and several senior professors, is set to announce the new academic calendar tomorrow."

Memory hook: this reinforces one final time that the sheer volume and plurality of nouns crammed into a parenthetical phrase has zero bearing on the verb — only the true subject before the phrase matters.

"A horse and carriage" is a fixed-pair concept (referring to one unified mode of transport), taking a singular verb — "were eventually replaced" is incorrect; it should be "was eventually replaced."

Correct sentence: "A horse and carriage, once the primary mode of transportation for the wealthy, was eventually replaced entirely by the automobile."

Memory hook: "a horse and carriage" completes your fixed-pair list (bread and butter, law and order, trial and error, slow and steady, a horse and carriage) — all five are worth memorising as a single group.

"Together with senior diplomatic staff from three neighbouring embassies" is a parenthetical phrase, so the verb agrees only with "the ambassador" (singular).

Correct sentence: "The ambassador, together with senior diplomatic staff from three neighbouring embassies, is hosting a reception this evening."

Memory hook: even a parenthetical phrase describing staff from multiple different embassies (implying a large, varied group) still doesn't change the underlying singular subject.

"Bread and butter" is the true subject here (a fixed-pair, singular concept), and "along with a simple cup of tea" is a parenthetical phrase that doesn't change this — "were the only refreshments" is incorrect; it should be "was the only refreshment" (though the marked segment as written focuses on the verb: "were" should be "was").

Correct sentence: "Bread and butter, along with a simple cup of tea, was the only refreshment served at the modest gathering."

Memory hook: a fixed pair combined with a parenthetical phrase stacks two singular-verb triggers on top of each other — both independently confirm the same singular outcome.

"The panel of judges" is the true subject — "panel" is a singular collective noun (with "of judges" as a prepositional distractor), and "in addition to a technical advisor..." is a further parenthetical phrase, so the verb remains singular.

Correct sentence: "The panel of judges, in addition to a technical advisor brought in specifically for the final round, is reviewing each contestant's submission carefully."

Memory hook: this question layers two separate rules — a collective noun subject ("panel," acting as a unit) PLUS a parenthetical phrase — both independently point to the same singular verb.

"The retiring principal and her successor" are joined by and, forming a genuine compound, plural subject (the clause "both of whom attended the same university decades apart" is a distractor) — "was honoured" is incorrect; it should be "were honoured."

Correct sentence: "The retiring principal and her successor, both of whom attended the same university decades apart, were honoured together at the farewell ceremony."

Memory hook: "both of whom" might look like it's reinforcing plurality, but the real reason for the plural verb is the and joining the two subjects, not this descriptive clause — always trace the actual subject connector.

"Slow and steady" functions here as the fixed-pair subject itself (referring to the philosophy as a single concept, reinforced by the appositive "the guiding philosophy..."), taking a singular verb.

Correct sentence: "Slow and steady, the guiding philosophy behind the company's decade-long expansion strategy, is once again proving more effective than aggressive, rapid growth."

Memory hook: when "slow and steady" is followed by an appositive phrase that explicitly renames it as a single "philosophy" or "approach," this confirms the fixed-pair, singular reading rather than the adjective-describing-another-noun reading tested at the intermediate level.

"Along with an entire team of nurses, anaesthetists, and support staff" is a parenthetical phrase (even with its own internal list joined by commas and "and"), so the verb agrees only with "the surgeon" (singular).

Correct sentence: "The surgeon, along with an entire team of nurses, anaesthetists, and support staff, is responsible for the patient's care throughout the twelve-hour operation."

Memory hook: a full list of multiple plural roles inside the parenthetical phrase is simply a longer, more elaborate distractor — the underlying rule remains completely unaffected by how many items the list contains.

"Along with two postdoctoral researchers..." is a parenthetical phrase, so the verb should agree only with "the lead scientist" (singular) — "remain confident" is incorrect; it should be "remains confident."

Correct sentence: "The lead scientist, along with two postdoctoral researchers whose work had been published extensively, remains confident about the study's findings."

Memory hook: a relative clause ("whose work had been published extensively") nested inside the parenthetical phrase adds further distance and complexity, but the core rule stays exactly the same — trace back past all the layers to the true subject.

"The two co-authors" is the true subject — already plural on its own — and "together with an independent fact-checker..." is a parenthetical phrase that doesn't change this, so the verb remains plural.

Correct sentence: "The two co-authors, together with an independent fact-checker hired specifically for this project, have verified every claim in the manuscript."

Memory hook: the parenthetical rule works both ways — it doesn't just keep a singular subject singular; it also doesn't turn an already-plural subject singular. The subject's own number, whatever it is, always wins.

"The negotiator and his opposite number" are joined by and, forming a genuine compound, plural subject (the participial phrase "having worked together..." is a distractor) — "was familiar" is incorrect; it should be "were familiar."

Correct sentence: "The negotiator and his opposite number from the rival firm, having worked together on three previous deals, were familiar with each other's style."

Memory hook: participial phrases ("having worked together") function as distractors the same way relative clauses do — neither changes a genuine and-joined compound subject into a singular one.

"Besides the admissions officer and two departmental coordinators" is a parenthetical phrase, so the verb agrees only with "the registrar" (singular).

Correct sentence: "The registrar, besides the admissions officer and two departmental coordinators, is processing applications throughout the holiday period."

Memory hook: this reinforces the "besides" pattern one final time with a multi-item, plural-heavy parenthetical phrase — the rule remains completely unaffected regardless of how packed the phrase becomes.

"A horse and carriage" is a fixed-pair concept, taking a singular verb, regardless of the descriptive participial phrase "meticulously restored by local historians" placed between the subject and the verb.

Correct sentence: "A horse and carriage, meticulously restored by local historians, is now on permanent display at the heritage museum."

Memory hook: reinforcing the fixed-pair rule one final time — no matter how much descriptive or historical detail surrounds "a horse and carriage," it remains a single, unified concept taking a singular verb.

"In addition to three staff reporters and a freelance photographer" is a parenthetical phrase, so the verb should agree only with "the chief editor" (singular) — "were dispatched" is incorrect; it should be "was dispatched."

Correct sentence: "The chief editor, in addition to three staff reporters and a freelance photographer, was dispatched to cover the unfolding crisis."

Memory hook: as a closing reinforcement of the entire topic — no matter how many named roles, professions, or people are packed into a parenthetical phrase, the true subject that appears before it is always what determines the verb.

"The two witnesses and the investigating officer" are joined by and, forming a genuine compound, plural subject.

Correct sentence: "The two witnesses and the investigating officer have each provided slightly different accounts of the same sequence of events."

Memory hook: even with "each" appearing later in the sentence (which independently signals singularity when it's the actual subject), here "each" functions as a distributive adverb describing how the plural subject acted individually — it doesn't override the plural subject-verb agreement already established by "and."

This sentence contains a logical/agreement mismatch: while "law and order" is normally a singular fixed pair, the complement "the two pillars" is explicitly plural, creating an internal contradiction — the intended meaning requires treating "law and order" and "infrastructure investment" as two separate, distinct pillars (not one fixed concept), so the verb should be plural: "remain."

Correct sentence: "Law and order, alongside sustained investment in public infrastructure, remain the two pillars of the administration's long-term strategy."

Memory hook: even a normally fixed, singular pair like "law and order" can be overridden by strong contextual evidence (like "the two pillars") that the sentence intends two separate things, not one unified concept — read for meaning, not just the fixed-phrase pattern.

"Together with the entire task force assembled specifically for this investigation" is a parenthetical phrase, so the verb agrees only with "the commissioner" (singular).

Correct sentence: "The commissioner, together with the entire task force assembled specifically for this investigation, is determined to bring those responsible to justice."

Memory hook: a lengthy, dramatic parenthetical phrase (common in news-style writing about investigations) is still just a parenthetical phrase — the drama and length of the sentence never change the grammatical mechanics underneath.

"The two shareholders" is the true subject — already plural on its own — and "as well as the company's outside legal counsel" is a parenthetical phrase that doesn't change this, so "was consulted" is incorrect; it should be "were consulted."

Correct sentence: "The two shareholders, as well as the company's outside legal counsel, were consulted extensively before the final terms were agreed upon."

Memory hook: as a final reinforcement across this entire topic — always identify whether the TRUE subject (before any parenthetical phrase) is singular or plural first; that number is what the verb must match, regardless of what follows.

"Trial and error" is the true subject, a fixed-pair singular concept, and "together with careful documentation of every failed attempt" is a parenthetical phrase that doesn't change this.

Correct sentence: "Trial and error, together with careful documentation of every failed attempt, is ultimately what led the team to the breakthrough."

Memory hook: as a final, comprehensive reinforcement — this sentence combines a fixed pair AND a parenthetical phrase, exactly like several earlier advanced questions, both independently confirming the same singular verb outcome.

"The two rival candidates" is the true subject — already plural on its own — and "along with their respective campaign managers" is a parenthetical phrase that doesn't change this, so "was seen" is incorrect; it should be "were seen."

Correct sentence: "The two rival candidates, along with their respective campaign managers, were seen shaking hands cordially before the televised debate began."

Memory hook: this reinforces the same lesson as Q20 — a parenthetical phrase never overrides the true subject's own number, whether that subject is singular or, as here, already plural.

"The auditor and her supervising partner" are joined by and, forming a genuine compound, plural subject (the relative clause "who had reviewed the accounts independently" is a distractor) — "was in complete agreement" is incorrect; it should be "were in complete agreement."

Correct sentence: "The auditor and her supervising partner, who had reviewed the accounts independently, were in complete agreement about the discrepancy."

Memory hook: this reinforces the earlier "novelist and editor" pattern — a relative clause interrupting a genuine compound subject joined by and doesn't change the fact that the verb must still be plural.

"In addition to industry representatives who had gathered for the annual conference" (the whole phrase, including its own embedded relative clause) is parenthetical, so the verb should agree only with "the regulator" (singular) — "were briefed" is incorrect; it should be "was briefed."

Correct sentence: "The regulator, in addition to industry representatives who had gathered for the annual conference, was briefed on the new compliance framework."

Memory hook: a relative clause nested inside a parenthetical phrase (describing the "representatives," not the main subject) is a distractor layered on top of a distractor — strip away both to find "the regulator" as the true, singular subject.
