Explanation:

The subject is the topic of a sentence, that is, what the sentence is about. The verb refers to the subject, expressing an action or a state/condition of that subject. For that reason, the verb and the subject must agree, that is, if the subject is singular, the verb should also be singular; if it is plural, the verb should also be plural.

Let's take sentence 5 as an example:

5. Mike, like many other students, have been trying to decide on the best gift to buy.

The phrase "like many other students" is what makes the sentence confusing. "Students" is a plural word and, because it is closer to the verb, we feel like using a plural verb as well. However, the subject is "Mike", which is a singular proper noun. Therefore, we should use a singular verb to agree with it. The correct sentence is:

- Mike, like many other students, has been trying to decide on the best gift to buy.
