Question

Identify the preposition in the following sentence and explain its function:

He'd never seen that vape pen before. Ben felt his heartbeat race and hot tears fill his eyes."

A never, expresses time
B that, introduces a noun clause
C race, describes an action
D before, shows a relationship in time

Answer 1

D — "before." It indicates a temporal relationship (he had not seen the vape pen previously), functioning adverbially to modify the verb phrase "had seen."
