Which choice completes the text so that it conforms to the conventions of Standard English?
A
it was
B
one was
C
they were
D
both were
Explanation
Correct answer: A.
Choice A is the best answer. The convention being tested is pronoun-antecedent agreement. The singular pronoun "it" agrees in number with the singular antecedent "the Salt Lake Temple."
Why the other choices are wrong
Choice B
Choice B is incorrect because the singular pronoun "one" is ambiguous in this context; the resulting sentence leaves unclear whether there is only one Salt Lake temple or multiple.
Choice C
Choice C is incorrect because the plural pronoun "they" doesn’t agree in number with the singular antecedent "the Salt Lake Temple."
Choice D
Choice D is incorrect because the plural pronoun "both" doesn’t agree in number with the singular antecedent "the Salt Lake Temple."
