readingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
produces
B
is producing
C
has produced
D
had produced
Correct Answer: D
Choice D is the best answer. This question tests verb tense in reported speech.
- Context clues: "Reported" (past) introduces information about an earlier event.
- Meaning: Use past perfect for an action that occurred before another past action.
- Verify: "reported that the experiment had produced" shows proper sequence.
💡 Strategy: In reported speech with past reporting verb, use past perfect for earlier actions.
Choice A is incorrect because present tense doesn't match past "reported." Choice B is incorrect because present progressive doesn't match past context. Choice C is incorrect because present perfect doesn't follow past "reported."
