What does the predicate of a sentence indicate? A. who is doing the action B. when the action is being done C. why the action is being done D. what is or what is happening

Your answer would be D.

Explanation:

The predicate of a sentence indicates what is or what is happening. The predicate is the part of the sentence or clause that tells us what the subject does or is. In other words, the predicate is everything that is not the subject. Therefore, in order to identify the predicate, you should first identify the subject. Ask the following question: who/what verb (ed) ? The answer to that question is the subject of the sentence. For instance, take A.

A) Mary bought a car yesterday

Who bought a car yesterday? The answer to this question is "Mary". The NP "Mary" is the subject of the sentence, making the VP "bought a car yesterday" the predicate.

The predicate Of a sentence is the part that modified the subject IS the person, place, or thing that a sentence is about, the predicate must contain a verb explaining what the subject does and can also include a modifier
