Answer: The revision that adds an adverb phrase is A. Many actors live with their families in Los Angeles.
Explanation: An adverb phrase is a group of words that modify a verb, an adjective or an adverb. It refers to why, when, where or in what way an action takes place. Moreover, an adverb phrase does not need to contain an adverb. Most times, an adverb phrase is made up of a preposition and a noun. <u>In sentence A., "with their families" is an adverb phrase since it is modifying the verb "live" and it is providing information related to the "how".</u> Furthermore, "with their families" is introduced by the preposition "with" and it contains a noun ("families").
