Which choice completes the text so that it conforms to the conventions of Standard English?
A
are identifying
B
identify
C
have identified
D

Explanation
Correct answer: D.
Choice D is the best answer. The convention being tested is subject-verb agreement. The singular verb "identifies" agrees in number with the singular subject "analysis."
Why the other choices are wrong

Choice A is incorrect because the plural verb "are identifying" doesn’t agree in number with the singular subject "analysis."
Choice B
Choice B is incorrect because the plural verb "identify" doesn’t agree in number with the singular subject "analysis."
Choice C
Choice C is incorrect because the plural verb "have identified" doesn’t agree in number with the singular subject "analysis."
