PASSAGE

The collection of rare stamps _______ on display at the museum until December.

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

A. are
B. were
C. is✓ Correct
D. have been

Detailed Answer Explanation

This question tests your understanding of sentence boundaries and punctuation. The subject is 'collection' (singular), not 'stamps.' Use singular 'is.' 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:

• "collection (singular)"

• "of rare stamps (prepositional phrase)"

Why others are wrong: D ('Have been' is plural.), A ('Are' is plural; doesn't match singular 'collection.'), B ('Were' is plural.).
