15. In the sentence 'Taylor sat under the tree,' what is the subject?

Answer: D

Explanation:

Taylor is the subject of the sentence.

The subject of the sentence 'Taylor sat under the tree' is Taylor, as it is the noun performing the action of sitting.

A) Sat

Sat is the verb of the sentence, indicating the action being performed. It does not function as the subject, which is the doer of the action.

B) Tree

Tree is a noun in the sentence, but it serves as the object of the preposition "under." It does not perform any action, hence it cannot be the subject.

C) Under

Under is a preposition that indicates the relationship between the subject and the object in the sentence. It does not represent the subject itself.

D) Taylor

Taylor is the correct subject of the sentence because it is the noun that performs the action of sitting, making it the central focus of the sentence.

Conclusion

In summary, Taylor is definitively the subject as it indicates who is performing the action in the sentence. All other options fail to identify the subject, either being verbs, objects, or prepositions that do not fulfill the role of the subject in the sentence.
