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.

Question 1easy

The intense heat that ______ from the core of the Earth is responsible for the movement of tectonic plates across the planet's surface. Which choice completes the text so that it conforms to the conventions of Standard English?

A)radiates
B)have radiated
C)radiate
D)are radiating

Show answer & explanation

Correct answer: A

Choice A is the best answer. The convention being tested is subject-verb agreement. The singular verb 'radiates' agrees in number with the singular subject 'heat.' Choice B is incorrect because the plural verb 'have radiated' doesn't agree in number with the singular subject 'heat.' Choice C is incorrect because the plural verb 'radiate' doesn't agree in number with the singular subject 'heat.' Choice D is incorrect because the plural verb 'are radiating' doesn't agree in number with the singular subject 'heat.'

Question 2medium

Professional Brazilian soccer player Marta Vieira da Silva inspired a generation of young athletes. In the 2000s, she rose to prominence with the Brazilian national team, which ______ of the most dominant forces in international women's soccer. Which choice completes the text so that it conforms to the conventions of Standard English?

A)were one
B)was one
C)were ones
D)are one

Show answer & explanation

Correct answer: B

Choice B is the best answer. The convention being tested is subject-verb agreement and agreement between nouns. The singular verb 'was' and the singular noun 'one' both agree in number with the relative pronoun 'which.' In this context, 'which' functions as a singular subject because it refers to the singular noun 'the Brazilian national team.' Choice A is incorrect because the plural verb 'were' doesn't agree in number with the singular noun phrase 'the Brazilian national team.' Choice D is incorrect because the plural verb 'are' doesn't agree in number and the present tense doesn't match the past tense context ('rose'). Choice C is incorrect because both the plural verb 'were' and the plural noun 'ones' don't agree in number with the singular noun phrase.

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.
