readingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
results, furthermore
B
results furthermore,
C
results; furthermore,
D
results: furthermore,
Correct Answer: C
Choice C is the best answer. This question tests punctuation with conjunctive adverbs.
- Context clues: Two independent clauses connected by "furthermore."
- Meaning: Use semicolon before and comma after a conjunctive adverb joining independent clauses.
- Verify: "The initial trials showed promising results; furthermore, additional testing confirmed..." is correct.
💡 Strategy: Conjunctive adverbs (furthermore, however, therefore) between independent clauses: semicolon + adverb + comma.
Choice A is incorrect because a comma before "furthermore" creates a comma splice. Choice B is incorrect because it lacks proper punctuation before "furthermore." Choice D is incorrect because a colon doesn't precede conjunctive adverbs.
