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

A

plan,

B

plan;

C

plan:

D

plan—

Correct Answer: D

Choice D is the best answer. This question tests dash usage for sudden shift or correction.

  1. Context clues: There's an abrupt qualification or correction of the statement.
  2. Meaning: A dash signals an abrupt change or afterthought.
  3. Verify: "Everything was proceeding according to plan—at least, that's what we thought" conveys the sudden qualification.

💡 Strategy: Use a dash to introduce an abrupt afterthought or correction.

Choice A is incorrect because a comma doesn't convey the abrupt shift. Choice B is incorrect because a semicolon suggests a smoother connection. Choice C is incorrect because a colon introduces explanation, not correction.
