Set 16: Boundaries
Explanation
PASSAGE
The archaeological discovery, which has attracted attention, _______ documented carefully.
Which choice completes the text so that it conforms to the conventions of Standard English?
Detailed Answer Explanation
The correct answer is 'has been' because of the rule: subject-verb agreement with singular subject. Subject-verb agreement is tested frequently on the SAT. Remember that the core subject determines the verb form, not any words appearing between the subject and verb. Prepositional phrases and relative clauses do not affect agreement.
Key Evidence:
• "The archaeological discovery, which has attracted attention,..."
Why others are wrong: B ('have been' is plural and does not agree with the singular subject), C ('were' is plural past tense and does not agree with the singular subject), D ('being' is a present participle and cannot serve as the main verb alone).
