Which choice completes the text so that it conforms to the conventions of Standard English?
A
have outlined
B
were outlining
C
outlines
D
outline
Explanation
Correct answer: C.
Choice C is the best answer. The convention being tested is subject-verb agreement. The singular verb “outlines” agrees in number with the singular subject “document.”
Why the other choices are wrong
Choice A
Choice A is incorrect because the plural verb “have outlined” doesn’t agree in number with the singular subject “document.”
Choice B
Choice B is incorrect because the plural verb “were outlining” doesn’t agree in number with the singular subject “document.”
Choice D
Choice D is incorrect because the plural verb “outline” doesn’t agree in number with the singular subject “document.”
