readingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
is destroyed
B
had been destroyed
C
has been destroyed
D
was being destroyed
Correct Answer: B
Choice B is the best answer. Use past perfect for events that occurred before the main past-tense narrative.
Choice A is incorrect because present passive doesn't match past context. Choice C is incorrect because present perfect doesn't fit past narrative. Choice D is incorrect because past progressive implies ongoing action.
