Solving Form, Structure, and Sense Questions on the SAT

The method: Find what must agree

Same stem as Boundaries (“conventions of Standard English”), different target: forms that must match, not clause punctuation. Identify the governor (subject, antecedent, main tense) and force the blank to obey it.

Use Governor → Match → Reread. Circle the true subject or antecedent (skip interrupters). Choose the form that matches. Reread for tense and modifier sense — a grammatically agreeing sentence can still dangle.

Subject–verb and intervening junk

Prepositional phrases, relative clauses, and “as well as…” add-ons are not the subject. Neither are titles or amounts that look plural (“Ten dollars is enough”). Collective nouns are usually singular in American usage on the SAT when the group acts as one.

Pronouns, tense, and modifiers

Pronouns need clear, matching antecedents (number and person). Tense should stay consistent unless the timeline shifts for a reason. Modifiers must sit next to what they describe — “Walking in, the paintings amazed me” wrongly makes paintings walk.

Spot the traps in the choices

Nearest-noun agreement, pronoun ambiguity, tense whiplash, and danglers. If two choices both “sound fine,” find the governor again — one of them usually matches the wrong word.

Practice until it’s automatic
