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

A

topics:

B

topics,

C

topics;

D

topics—

Correct Answer: A

Choice A is the best answer. This question tests colon usage before a list.

  1. Context clues: A complete sentence introduces a list of items.
  2. Meaning: Use a colon after a complete sentence to introduce a list.
  3. Verify: "The conference will address several critical topics: climate change mitigation, renewable energy adoption, and sustainable urban development" correctly introduces the list.

💡 Strategy: A colon can introduce a list when preceded by a complete sentence.

Choice B is incorrect because a comma cannot properly introduce this formal list. Choice C is incorrect because semicolons don't introduce lists. Choice D is incorrect because while a dash could work informally, a colon is more appropriate for formal lists.
