writingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
indication
B
indicators
C
sign
D
signal
Correct Answer: B
Choice B is the best answer. The subject includes two distinct trends ("expansion" and "popularity"), making it plural. Therefore, the noun referring to them must be plural ("indicators").
Choice A is incorrect because "indication" is singular. Choice C is incorrect because "sign" is singular. Choice D is incorrect because "signal" is singular.
