readingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
that contain classified information
B
, that contain classified information,
C
, which contain classified information,
D
which contain classified information
Correct Answer: A
Choice A is the best answer. This question tests "that" for essential clauses.
- Context clues: The clause identifies WHICH documents will remain sealed—essential.
- Meaning: Use "that" without commas for essential (restrictive) clauses.
- Verify: "The documents that contain classified information will remain sealed" specifies which documents.
đŸ’¡ Strategy: Use "that" without commas when the clause is essential to identify the noun.
Choice B is incorrect because "that" shouldn't have commas. Choice C is incorrect because "which" with commas makes it nonessential, changing the meaning. Choice D is incorrect because "which" alone is less preferred for restrictive clauses.
