The books _______ are on the top shelf have been donated to the library.
Which choice completes the text so that it conforms to the conventions of Standard English?
that are on the top shelf
, that are on the top shelf,
, which are on the top shelf,
which are on the top shelf
Correct Answer: A
Choice A is the best answer. This question tests "that" for essential (restrictive) clauses.
- Context clues: The clause identifies WHICH books were donated—essential information.
- Meaning: Use "that" without commas for restrictive clauses.
- Verify: "The books that are on the top shelf have been donated" correctly limits which books.
đŸ’¡ Strategy: Use "that" without commas for essential information; use ", which" for nonessential.
Choice B is incorrect because "that" shouldn't have commas for restrictive clauses. Choice C is incorrect because the clause is essential (identifies which books), not nonessential. Choice D is incorrect because "which" without commas is inconsistent.
