Final answer:
The subject of the sentence is "Mrs. Hammerstone and the other members," and the predicate is "left the meeting in a fit of rage." The subject names the doers of the action, and the predicate contains the verb and describes the action they are taking.
Step-by-step explanation:
The sentence in question is "Mrs. Hammerstone, and the other members, left the meeting in a fit of rage". To identify the subject and predicate of this sentence, we first look at the main noun or noun phrase that the sentence is about, which is the subject, and then identify the predicate which tells us what the subject does or is like.
In this example, "Mrs. Hammerstone and the other members" is the subject of the sentence because it refers to the people who are doing the action. "Left the meeting in a fit of rage" is the predicate, because it contains the verb "left" and describes the action taken by the subject.
Remember that in English, subjects and verbs must agree. If the subject is singular, the verb must also be in its singular form, and if the subject is plural, then a plural verb form is used. This is known as subject-verb agreement.
