Answer:
1. Everyone is a subject. (A)
2. Both is a subject. (A)
3. All is a subject. (A)
Step-by-step explanation:
The subject is the topic of a sentence, that is, what that sentence is about. To find the subject, we can ask questions to the verb. Let's do that for each sentence given in the question:
1. Everyone named him the best. singer. --> Who performed the action? Who named him the best singer? Everyone. --> Everyone is the subject.
2. Both of the girls forgot their bags. --> Who performed the action? Who forgot their bags? Both (of the girls). --> Both is the subject.
3. Not all were late tonight; some were actually early. --> Who performed the action? Who were late tonight? (Not) all. --> All is the subject.
If any doubt remains, take a look at the following definitions. They will help you see that none of the other options is correct.
- A subject complement is a word or phrase which describes the subject. It comes after a linking verb (to be, to become, to feel, to look, etc.).
- The direct object is the receiver of the verb's action. For instance: She cooked the meal ("meal" is the object of "cooked").
- The object of a preposition is a noun or pronoun that follows a preposition in a sentence.
