Which choice completes the text so that it conforms to the conventions of Standard English?
A
animates
B
have animated
C
animate
D
animating
Explanation
Correct answer: A.
Choice A is the best answer. The convention being tested is subject-verb agreement. The singular verb "animates" agrees in number with the singular subject "question."
Why the other choices are wrong
Choice B
Choice B is incorrect because the plural verb "have animated" doesn’t agree in number with the singular subject "question."
Choice C
Choice C is incorrect because the plural verb "animate" doesn’t agree in number with the singular subject "question."
Choice D
Choice D is incorrect because it results in an ungrammatical sentence. The nonfinite participle "animating" doesn’t supply the clause with a finite verb.
