PASSAGE

None of the cookies _______ left after the party.

Which choice completes the text so that it conforms to the conventions of Standard English?

A. were✓ Correct
B. is
C. was
D. has been

Detailed Answer Explanation

This question tests your understanding of sentence boundaries and punctuation. When 'none' refers to a countable plural noun (cookies), it takes a plural verb. Use '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:

• "none of the cookies (countable plural)"

Why others are wrong: B ('Is' is singular and present tense.), C ('Was' is singular; 'cookies' are countable, so use plural.), D ('Has been' is singular.).
