I believe that the narrator is annoyed. She doesn't really like May Day, and is relieved she doesn't have to be a part of it. However, her mom still wants her too.
"A. The ancestor of the dog." is a fragment. When in doubt, say the sentence out loud and ask yourself if there is enough information for the sentence to make sense.
Let us dissect each sentence to tell which of these does not follow the rules for subject-verb agreement.
A.) The subject is 'each of the students' while the verb is 'is'. More particularly, the verb refers to 'each' which is singular. So, this is correct.
B.) The subject is 'student' while the verb is 'were'. The word 'were' is the paste tense of are which is used for a plural subject. But since student is singular, then the verb should have been 'was'. So, this is incorrect.
C.) The subject is 'my dog and my cat' which pertains to two nouns, thus it is plural. It agrees with its plural verb 'are'.
D.) The subject is 'Tom' while the verb is 'does'. Both are intended for singular use. So, this is correct.
Therefore, the answer to this is letter B.
The correct answer is D. Setting
The setting is the time, place, and situation of a story. It is described or put forth in the introduction of a story.
