Set 7: Boundaries
Explanation
PASSAGE
The acoustics of the concert _______ carefully designed to ensure optimal sound quality from every seat.
Which choice completes the text so that it conforms to the conventions of Standard English?
Detailed Answer Explanation
This question tests your understanding of sentence boundaries and punctuation. 'Acoustics' as a quality of a space is plural. Use plural 'were.' To determine the correct answer, examine where complete thoughts begin and end. Look for independent clauses that need proper separation. A period, semicolon, or appropriate conjunction can correctly join or separate these ideas. When analyzing sentence boundaries, pay attention to how ideas flow from one sentence to the next. Correct punctuation ensures clarity and prevents confusion for readers. Review the options carefully to identify which choice creates proper sentence structure.
Key Evidence:
• "acoustics (plural when describing sound quality)"
Why others are wrong: A ('Was' is singular; 'acoustics' as quality is plural.), B (Comma incorrect AND 'was' is singular.), C (Comma incorrectly separates prepositional phrase from verb.).
