Set 12: Boundaries
Explanation
PASSAGE
The books on the top _______ for advanced readers only.
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. The subject is 'books' (plural), not 'shelf.' Use plural 'are.' No punctuation separates subject from verb. 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:
• "books (plural subject)"
• "on the top shelf (prepositional phrase)"
Why others are wrong: D ('Is' is singular; doesn't match plural 'books.'), A (Colon is grammatically incorrect here.), B (Comma incorrectly separates phrase from verb, AND 'is' is singular.).
