Answer:
Which sentence includes a gerund?
Swimming in the gulf is Finn's favorite summer activity.
Explanation:
Grammatically, a gerund is a verb form that functions as a noun. "Swimming" in the gulf is a noun phrase and the "swimming" in the phrase is a gerund because it functions as a noun. Ordinarily and in the second and third sentences, the word "swimming" is a continuous form of the verb, "swim." In the fourth sentence, the word swimming functions as a part of the adjectival phrase "community swimming" to explain the type of pool under reference.
