TOEIC Link Reading Part 5 — Subject-Verb Agreement When a Phrase Gets in the Way

One of the most reliable ways TOEIC Link Part 5 catches careful readers is not by testing a hard rule but by putting distance between the subject and the verb. The rule itself — a singular subject takes a singular verb, a plural subject takes a plural verb — is one you already know. The difficulty is that the test rarely places the subject next to the blank. Instead it drops a prepositional phrase, a relative clause, or a modifier in between, so that the noun sitting immediately before the verb is not the noun that controls it. If you agree the verb with whatever word happens to be nearest, you have done exactly what the item was built to make you do.

The trap in one sentence

Look at this stem:

"The list of approved vendors and preferred suppliers ___ updated every quarter." (A) are (B) were (C) is (D) have been

The word right before the blank is suppliers — plural. So are and have been both feel natural to the ear. But suppliers is not the subject. The subject is list, which is singular, and everything from of onward is a prepositional phrase describing the list. Strip it out and the sentence is simply "The list ... is updated every quarter." The answer is (C). The plural nouns were placed there precisely to pull your agreement toward the wrong number.

The method: bracket the intervening phrase

The fix is mechanical, and it is the same discipline behind reading the slot before you weigh meaning in preposition-versus-conjunction items: you decide by structure, not by what sounds smooth.

1. Find the verb (or the blank where the verb goes).
2. Move left to the first noun, then keep going — ignore anything inside a phrase that starts with of, with, including, along with, as well as, or a relative pronoun (who / which / that).
3. The first noun that is not trapped inside such a phrase is your head noun. Agree with that.

Applied to the example: the verb is updated; moving left you hit suppliers (inside of ...suppliers), then vendors (same phrase), then list — the first noun outside the of phrase. Head noun = list = singular.

The three patterns tested most often

1. Prepositional phrase between subject and verb

This is the version above. The head noun comes before a phrase beginning with of, in, on, for, between, etc.

"The quality of the components ___ inspected on arrival." → is (quality is singular)

2. "as well as / along with / together with" — these do NOT make a subject plural

Phrases like as well as, along with, in addition to, and together with look like and, but grammatically they are add-ons, not part of the subject. The verb agrees with the original subject only.

"The manager, along with two assistants, ___ attending the conference." → is (subject is still manager)

Contrast this with a true and: "The manager and two assistants are attending" — there, and genuinely creates a plural subject.

3. "One of the [plural noun]" — the subject is one, singular

"One of the reports ___ missing a signature." → is

Students almost always want are here because reports is plural and adjacent. But the subject is one. The of the reports phrase only tells you which group the one belongs to. Watch, however, for the sister pattern "those of the reports that are ..." inside a relative clause, where a plural verb is correct because a different noun controls it.

A quick decision checklist

Practice the reflex, not the rule

You do not need to relearn agreement; you need to stop trusting proximity. On every Part 5 verb item, ask one question before you look at the choices: what is the real subject, and is it singular or plural? Answer that with the phrase bracketed out, and the four options collapse to one. This is the same "find the controlling word first" habit that makes matching verb tense to the time marker fast and reliable — in both cases, the sentence hands you the answer before you ever consider which form "sounds right."

Train it deliberately: for the next block of Part 5 questions you do, underline the head noun before choosing, even on items where agreement is obvious. Making the step explicit is what turns it into an automatic move under time pressure on test day.
