Subject-verb agreement and pronoun reference
Correct Answer
B
This choice represents the only logical and grammatically compliant solution.
Step-by-Step Solution Guide
- Identify the error being tested by looking at the differences in the answer choices. Notice that they differ in punctuation, verb tense, or pronoun number.
- Analyze the structure of the surrounding sentence. Identify the main subject and verb, and locate any dependent clauses or modifying phrases.
- Apply the grammatical rule: Verify if the subject is singular or plural, or check if the punctuation correctly separates independent clauses.
- Choose the most concise and grammatically correct option. Avoid redundant phrasing.
Detailed Answer Breakdown
Choice B (Correct)
Choice B is correct because it maintains grammatical parallel structure and uses punctuation that correctly links the clauses without creating a run-on or comma splice.
Choice C (Incorrect)
This choice is incorrect because it creates a comma splice, linking two independent clauses with only a comma.
Choice D (Incorrect)
This choice is incorrect because it uses a plural verb, which violates subject-verb agreement with the singular main subject.
Choice A (Incorrect)
This choice is incorrect because it is unnecessarily wordy and repeats information already stated in the sentence.
Key Learning Point
The SAT writing section values conciseness. If multiple options are grammatically correct, the shortest one that conveys the complete meaning is almost always the correct answer.
