The scientist's research, which is focused on the impact of climate change on coral reefs, ______ a variety of complex factors.
Which choice completes the text so that it conforms to the conventions of Standard English?
Correct answer: A
Explanation
The correct answer is "involves." The sentence requires a finite verb to modify the noun phrase "the scientist’s research." The participle "involving" would be incorrect because it's a nonfinite verb. The past participle "involved" would be incorrect because it suggests the action has already been completed. "To involve" would be incorrect because it's a nonfinite to-infinitive. Of these choices, only the present tense verb "involves" makes sense in the context.
