What the SAT Actually Tests

This category covers agreement and form: subject-verb agreement (especially with prepositional phrases between them), verb tense consistency, pronoun-antecedent agreement, apostrophes and possessives, and dangling or misplaced modifiers.

For agreement, mentally delete everything between the subject and the verb — 'the collection of rare paintings WAS' — because the interrupting phrase is where the trap lives. For modifiers, whoever performs the opening phrase's action must appear immediately after the comma. For its/it's and their/they're, expand the contraction and check whether the sentence still reads.

Traps to Avoid

Matching the verb to the nearest noun instead of the actual subject buried before a prepositional phrase.
Letting an opening modifier dangle: 'Walking to school, the rain soaked her' has the rain doing the walking.
Using 'it's' for possession — the possessive of it never takes an apostrophe.
