What are the seven subject and verb agreement rules

RULE1: The subject and verb must agree in number: both must be singular, or both must be plural.

Example:The car belongs to my brother.(SINGULAR)

They also play football.(PLURAL)

RULE2: The number of the subject (singular or plural) is not changed by words(or a phrase) that come in between the subject and the verb.

Example: One of the boxes is open.

Here,the subject “one” and the verb “is” are both singular.

RULE3: Some subjects always take a singular verb even though the meaning may seem plural.

Example: Someone in the game was (not were) hurt.

RULE4: The following words may be singular or plural, depending upon their use in a sentence: some,any, all, most.

Example: Most of the news is good. (singular)

Most of the flowers were yellow. (plural)

RULE5: Subjects joined by “and” are plural. Subjects joined by “or” or “Nor” take a verb that agrees with the last subject.

Example: Bob and George are leaving.

Neither Bob nor George is leaving.

RULE6: “There” and “here” are never subjects.In sentences that begin with these words, the subject is usually found later on in the sentence.

Example: There were five books on the shelf. (were, agrees with the subject “book”)

RULE7: Collective nouns may be singular or plural, depending on their use in the sentence.

Examples: The orchestra is playing a hit song. (Orchestra is considered as one unit—singular)

The orchestra were asked to give their musical backgrounds. (Orchestra is considered as separate units-plural)

Explanation:

answer; ///i believe the answer your looking for and the correct answer is (d); / he becomes very angry;

halibut, flounder, tuna, and trout are all fish. so your first answer is 1.) fish. and since fish is edible, your next answer would be 3). edible

to describe those fishes more thoroughly, some of those fishes live in fresh water, and some of the fishes live in salt water, and that is not a thing that they all have in common. the question is asking what is common with all of the fish, so answer choices 2). fresh water and 4). salt water are not right.
