writingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
tasks
B
role
C
assignments
D
duties
Correct Answer: B
Choice B is the best answer. The subject refers to a single function ("main..."), so the singular noun "role" is correct.
Choice A is incorrect because "tasks" is plural. Choice C is incorrect because "assignments" is plural. Choice D is incorrect because "duties" is plural.
