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

A. dish which changes seasonally,
B. dish, which changes seasonally
C. dish which changes seasonally
D. dish, which changes seasonally,✓ Correct

Detailed Answer Explanation

This question tests your understanding of sentence boundaries and punctuation. 'Which changes seasonally' is a nonessential clause (extra info). Nonessential clauses need commas on BOTH sides. 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:

• "which (nonessential clause)"

• "commas on both sides"

Why others are wrong: A (Missing opening comma before 'which.'), B (Missing closing comma after 'seasonally.'), C (Missing both commas around nonessential clause.).
