Final answer:
In the sentence provided, 'Mark' is the subject as he is the one performing the action of taking others for a ride. The subject is typically the focus of the sentence and agrees in number with the verb.
Step-by-step explanation:
The subject of a sentence is the person, place, thing, or idea that is doing or being something. The predicate contains the verb and tells something about the subject. In the sentence 'Mark took Sue, Jim, and Jane for a ride in a Tesla,' Mark is the subject because it is Mark who is performing the action of taking others for a ride. Hence, the answer to the question is option 1) Subject.
Subjects are the focus of the sentence and are typically found at the beginning. In standard English grammar, it is essential for subjects and verbs to agree in number, meaning a singular subject pairs with a singular verb and a plural subject with a plural verb. The subject can be a noun, a pronoun, or a noun phrase, which may include adjectives or determiners. For instance, in 'We went to the bowling alley on Friday,' 'We' is the subject, and in 'The meeting is at noon,' 'The meeting' is the subject.
