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

A

B

C

D


Correct Answer: D

Your Answer:

Explanation

D

In this Rules question, periods and question marks are changing in the answer choices, so it's testing questions versus statements. The beginning of the sentence provides a statement that says The timings of the discovery and these political changes led many to wonder, so the second part of the sentence should be a statement. Eliminate answers that aren't correctly written as statements.

  • (A) and (B) are wrong because they are questions.

  • (C) is wrong because, although it is a statement, it makes the sentence incomplete.

  • (D) is correct because it's correctly written as a statement that makes the sentence complete.
