What do you think?

To identify which of these sentences has an intransitive verb, we need to understand the difference between transitive and intransitive verbs.

A transitive verb is a verb that requires a direct object to complete its meaning. In other words, it shows an action done to someone or something.
An intransitive verb, on the other hand, does not require a direct object and can stand alone in a sentence. It shows an action or a state of being.

Let's analyze each sentence:

A. Paul returned the tools, today.
In this sentence, the verb "returned" is transitive because it requires a direct object, which is "the tools." Therefore, sentence A does not contain an intransitive verb.

B. I lost my cell phone at the park.
In this sentence, the verb "lost" is also transitive because it requires a direct object, which is "my cell phone." Therefore, sentence B does not contain an intransitive verb.

C. Stephanie found it later.
In this sentence, the verb "found" is transitive because it requires a direct object, which is "it." Therefore, sentence C does not contain an intransitive verb.

D. Romy never swam in the ocean.
In this sentence, the verb "swam" is intransitive because it does not require a direct object. It stands alone and shows the action of swimming. Therefore, sentence D contains an intransitive verb.

Therefore, the correct answer is D. Romy never swam in the ocean.
