readingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
finding:
B
finding,
C
finding;
D
finding—
Correct Answer: A
Choice A is the best answer. This question tests colon usage to introduce an explanation.
- Context clues: A complete sentence is followed by an explanation of the "unexpected finding."
- Meaning: A colon can follow a complete sentence to introduce an explanation.
- Verify: "The research revealed an unexpected finding: participants who exercised..." correctly introduces what the finding was.
đź’ˇ Strategy: Use a colon after a complete sentence when what follows explains or elaborates on it.
Choice B is incorrect because a comma creates potential for confusion. Choice C is incorrect because a semicolon suggests equal ideas, not explanation. Choice D is incorrect because while a dash works, a colon is more appropriate for explanation.
