readingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
effective,
B
effective;
C
effective:
D
effective—
Correct Answer: A
Choice A is the best answer. This question tests comma usage before dependent clauses at the end.
- Context clues: An "although" clause follows the main clause.
- Meaning: When a dependent clause providing contrasting information follows the main clause, a comma is optional but preferred.
- Verify: "The medication proved effective, although some patients reported minor side effects" provides smooth contrast.
💡 Strategy: Use a comma before a final contrasting dependent clause for clarity.
Choice B is incorrect because a semicolon cannot precede a dependent clause. Choice C is incorrect because a colon doesn't introduce dependent clauses. Choice D is incorrect because a dash provides more dramatic separation than needed.
