You read the sentence, "were" sounds right, you pick it, and it's wrong. Agreement questions make prepared students feel careless, because the wrong answer is engineered to sound better than the right one. The fix is mechanical: one method, The Cross-Out, plus one short list of words that lie to your ear.
Agreement is one of the four rules that decide most SAT grammar questions — and it's the one aimed squarely at your ear.
The trap: the SAT buries the subject on purpose
An SAT agreement question is rarely asking "does this verb match this subject?" It's asking "can you find the subject at all?" The test inserts a prepositional phrase, an appositive, or a parenthetical between the subject and the verb, and that interrupter usually carries a noun of the opposite number from the real subject.
The stack of unread applications sit on her desk.
"Applications sit" sounds perfect. But applications isn't the subject — it's the object of of. The subject is stack. The stack sits.
Why does this fool people who know the rule cold? Working-memory limits — real cognitive science, not a metaphor. You can hold only a few chunks of a sentence at once, so by the time you reach the verb, the noun you're still holding is the nearest one, not the true subject. The test is checking whether proximity can hijack your judgment. Trying harder doesn't help. A procedure does.
The Cross-Out
Three steps, every time:
- Find the verb being tested.
- Cross out everything between the subject and the verb. Physically. That means any phrase starting with of, in, with, for, from, including, as well as, along with, in addition to — and anything set off by a pair of commas.
- Read what's left, and match.
The recipe for the bakery's best-selling pastries call for imported butter.
Cross out for the bakery's best-selling pastries: "The recipe calls." The plural pastries never gets a vote.
The director, along with three producers, are attending the premiere.
Cross out the comma-wrapped phrase: "The director is attending." Worth memorizing: along with, as well as, and in addition to never make a subject plural. Only and does that.
That comma-wrapped interrupter should look familiar — it's the same removable extra information the Delete Test checks on punctuation questions; here you delete it to expose the subject instead. The burying phrases are also modifiers, and modifiers have their own failure mode when they attach to the wrong noun — covered in the dangling modifiers guide.
The hard version stacks decoys:
The archive of letters from the expedition's early years were digitized last spring.
Two plural nouns (letters, years) stand between you and the verb. Cross out both phrases: "The archive was digitized." On harder questions the decoy is sometimes the same number as the subject, so "pick the noun that sounds different" is not a strategy. Finding the subject is.
The Liars List
Five liars break everyone's ear: each, every, everyone, anyone, a team/company/group. All singular. Always.
Spoken English lets you say "everyone brought their laptop," so your ear has years of training in the wrong direction. The SAT grades the formal convention: each is singular even when a plural phrase follows it. Run the Cross-Out on "Each of the paintings were restored" — strike of the paintings — and "Each were" exposes itself. Each was. Collectives work the same way: a team wins, a company raises its prices, a committee issues its report. One unit, singular everything.
Pronouns: the same move, with an arrow
Pronoun-antecedent agreement is the identical skill in a different costume. Instead of crossing out, draw an arrow from the pronoun back to the exact noun it stands for — not the plural noun sitting next to it — and match number to that.
Each of the startups presented their prototype to the panel.
Arrow from their: it stands for each, not startups. Each is singular — it's on The Liars List — so the sentence needs its prototype. Sounds robotic; still correct.
Same arrow for institutions: "The museum expanded their collection" — the pronoun stands for museum, one institution, so it's its collection. Never let a pronoun float free. If you can't physically point at its noun, you're guessing.
Noun number: the third face of the rule
Sometimes the tested word is the noun itself, and the determiner in front of it is the boss. Each of, one of, both of, several of all require "of the + plural noun."
Each of the telescope was aimed at a different star.
Wrong — the construction demands telescopes. The layered trap: the corrected sentence, "Each of the telescopes was aimed," pairs a plural noun with a singular verb, and both are right. Two rules, two words, checked separately: the noun answers to its determiner, the verb answers to its subject (each). Don't let the correct singular verb talk you into "fixing" the correct plural noun.
The self-test: The Cross-Out audit (run it today)
Pull your last scored practice test, or any set of ten agreement questions.
- Autopsy your misses. For every agreement question you got wrong, look at the noun nearest the verb. Count how many times that nearest noun was a different number from the true subject. That count is proximity taking points from you — not carelessness, one specific mechanic with a name.
- Redo ten fresh questions with the Cross-Out mandatory. Physically strike the interrupters, even when the answer looks obvious.
If the crossed-out set beats your normal accuracy, you've located the leak and its fix in one sitting.
