readingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
, therefore
B
therefore
C
, therefore,
D
therefore,
Correct Answer: C
Choice C is the best answer. This question tests comma usage with "therefore" as a parenthetical.
- Context clues: "Therefore" interrupts a single sentence as a parenthetical element.
- Meaning: When "therefore" appears mid-sentence as an interrupter, set it off with commas on both sides.
- Verify: "The data, therefore, supports the original hypothesis" correctly brackets "therefore."
💡 Strategy: When "therefore" interrupts a sentence (not joining independent clauses), use commas on both sides.
Choice A is incorrect because it lacks the closing comma. Choice B is incorrect because it lacks both commas. Choice D is incorrect because it lacks the opening comma.
