Which of the following sentences contains an adverb?

The sentence "She sings beautifully" contains the adverb "beautifully," which modifies the verb "sings." Adverbs often provide additional information about how an action is performed, and in this case, "beautifully" describes the manner of singing, indicating that her singing is done in a beautiful way.

In contrast, the other sentences do not contain adverbs. For example, "Tom ran home" uses "home" as a noun indicating a place rather than describing how he ran. In "He is a tall man," "tall" is an adjective describing the noun "man," and it provides information about his physical stature, not the manner of an action. Lastly, "We went to the store" is structured with "to the store" functioning as a prepositional phrase indicating destination, without an adverb describing the going action.
