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

A

results, thus

B

results thus,

C

results; thus,

D

results: thus,

Correct Answer: C

Choice C is the best answer. This question tests punctuation with conjunctive adverbs.

  1. Context clues: Two independent clauses connected by "thus."
  2. Meaning: Use semicolon before and comma after conjunctive adverbs joining independent clauses.
  3. Verify: "...failed to produce consistent results; thus, the researchers decided..." is correct.

💡 Strategy: Use semicolon + conjunctive adverb + comma between independent clauses.

Choice A is incorrect because a comma before "thus" creates a comma splice. Choice B is incorrect because it lacks the semicolon. Choice D is incorrect because colons don't precede conjunctive adverbs.
