Which choice completes the text so that it conforms to the conventions of Standard English?
A
they
B
one
C
you
D
it
Explanation
Correct answer: A.
Choice A is the best answer. The convention being tested is pronoun–antecedent agreement. The plural pronoun “they” agrees in number with the plural antecedent “customers.”
Why the other choices are wrong
Choice B
Choice B is incorrect because the singular pronoun “one” doesn’t agree in number with the plural antecedent “customers.”
Choice C
Choice C is incorrect because the second person pronoun “you” isn’t conventional as a substitute for “customers.” It suggests that the audience (“you”) is the customer.
Choice D
Choice D is incorrect because the singular pronoun “it” doesn’t agree in number with the plural antecedent “customers.”
