Which of the following sentences contains a gerund?

1. He started to sing

2. Running is my favorite hobby

3. She will write her paper

4. They are playing soccer

The correct answer is: Running is my favorite hobby

The correct choice highlights a gerund, which is a verb form ending in -ing that functions as a noun. In the selected sentence, "Running" is the subject of the sentence and captures the essence of a gerund by representing an activity while also serving as a noun. This fits the definition of a gerund perfectly as it indicates an ongoing action and emphasizes that the activity of running is regarded as a hobby. The other sentences do not contain gerunds. In the first sentence, "to sing" functions as an infinitive rather than a gerund. The third sentence uses "write" as a base verb, and in the fourth sentence, "playing" is part of a continuous verb phrase but does not represent the action as a noun on its own within the context. Thus, the second option stands out as the only sentence that correctly utilizes a gerund.
