In which one of these sentences does an adverb modify a verb?

A. Lucy quickly hid behind the tree.
B. The dress was terribly old.
C. Jacob was a very smart boy.
D. Mr. Dodge moved in an extremely slow manner.
I think it's A?

You are correct.

Thanks :P

You're welcome.

You're correct! In sentence A, the adverb "quickly" modifies the verb "hid." To identify when an adverb modifies a verb, you should look for words that describe how the action of the verb is performed. In this case, "quickly" describes how Lucy hid behind the tree, indicating the speed of the action. Therefore, sentence A demonstrates the use of an adverb modifying a verb.
