readingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
facilitated
B
having facilitated
C
to facilitate
D
facilitating
Correct Answer: A
Choice A is the best answer. The nonrestrictive clause "which facilitated..." modifies the noun phrase "development of the first compiler." The verb in this clause must agree with the past context of Hopper’s historical achievement. "Facilitated" is the simple past tense verb that correctly indicates a completed action.
