The sentence that contains an error in subject-verb agreement is the following one: Most of the class eat lunch at school.
Explanation:
Subject verb agreement means that the verb and the subject must agree in number. This means that both need to be singular or both need to be plural. In the sentence above, the subject and the verb do not agree in number. In order to identify this problem, you need to identify the subject of the sentence.
The subject of the sentence is the NP "most of the class". The verb should agree in number with the noun head, which is "class". "Class" is a collective noun, so you should take into account that it can be used to refer a group as a unit or to its members as individuals. In this case, the noun refers to whole group, so the verb should be treated as singular and should contain the -s. The revised version of the sentence would be as follows: Most of the class eats lunch at school.
Nature helped in both stories with the tree that absorbed tears and the pine tree that grew in the place of the boy that was sucked into the ground. The genres of both stories you could say are folk tale and lesson to be learned. There are metaphors and similes throughout both of the stories. You could say the tree that grew in place of the boy was a sign of the boy's former life. The tree that absorbed the girls tears took away all of her sadness.
