Question

In which sentence is the word swimming a gerund? The children were swimming in the shallow end of the pool.The swimming team members warmed up before the meet.Swimming is great cardiovascular exercise.

Answer 1

Swimming is great cardiovascular exercise.

Step-by-step explanation:

A gerund is a verb that ends with the ing form (or the present participle form), however, it does not act as a verb but as a noun. In the sentence "Swimming" is acting as a noun (It refers to the skill of swimming or the sport of swimming itself) and it's the subject as well as it is what is being dealt with in the sentence.

Answer 2

The correct answer is C. Swimming is great cardiovascular exercise.

In this sentence, "swimming" is a gerund. It functions as the subject of the sentence. In the first option, "swimming" is part of the verb phrase ("were swimming"). In the second option, "swimming" is part of the adjective and describes the team. Only in the final sentence does "swimming" function as a noun, or a gerund.
