Question

Identify the adverb clause in the following sentence. Before automobiles came on the scene, people often used horses as transportation.
a. Before automobiles came on the scene
b. on the scene
c. often used horses
d. people often used horses as transportation

Answer 1

There is one adverb in this sentence - "often", but it's not part of the advern phrase.

The whole adverb phrase actually does not contain an adverb - it's "Before automobiles came on the scene" - answer a) . It's an adverb phrase because it answers the question of "when"
