Set 16: Boundaries

Explanation

Answer: B

PASSAGE

Sarah wanted to visit the historical site _______ she didn't have enough time.

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

A. : but
B. , but✓ Correct
C. ; but
D. but

Detailed Answer Explanation

The correct answer is ', but' because of the rule: comma before coordinating conjunction joining independent clauses. When two independent clauses are joined by a coordinating conjunction (for, and, nor, but, or, yet, so—FANBOYS), a comma must precede the conjunction. This creates a compound sentence with proper punctuation.

Key Evidence:

• "Sarah wanted to visit the historical site _______ she didn't..."

Why others are wrong: A (': but' incorrectly uses a colon, which is not used before coordinating conjunctions), C ('; but' incorrectly uses a semicolon, which should not precede a coordinating conjunction), D ('but' lacks the required comma before the coordinating conjunction).
