Answer:
The adverb in the sentence is "again."
Explanation:
An adverb is a part of speech that modifies or describes a verb, an adjective, or another adverb. It provides information about the manner, place, time, degree, or frequency of an action. For example, in the sentence "She sings beautifully," the adverb "beautifully" modifies the verb "sings" by providing information about how she sings.
