Set 10: Boundaries (Advanced)
Explanation
PASSAGE
The orchestra _______ rehearsing for the concert every evening this week.
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. 'Orchestra' is a collective noun treated as singular when acting as a unit. Use singular 'has been.' 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:
• "orchestra (collective noun, singular)"
Why others are wrong: B ('Have been' is plural; collective noun takes singular.), D ('Were' is plural and past tense.), A ('Are' is plural.).
