Every subject-verb agreement trap
Is my subject singular or plural? The places the answer isn't the noun right before the verb.
Find the real subject before you choose the verb. Cross out any phrase between the subject and the verb (of the students, along with his friends); the verb agrees with what's left. Words like each, everyone, and nobody are singular. Two subjects joined by and are plural, but with or or nor the verb agrees with the nearer one. A collective noun like team takes a singular verb when the group acts as one unit. The number of is singular and a number of is plural. In a question or a there is/there are sentence, the subject comes after the verb, so find it before you pick is or are.
The subject is hiding
Example
A phrase wedged between subject and verb never changes the verb.
Singular or plural?
Example
each, everyone, somebody, and nobody are singular.
Example
Singular when the group acts as one unit.

Joined by and, plural; joined by or/nor, the verb agrees with the closer noun.
The same question for pronouns
Example
A pronoun agrees in number with the noun it points back to.
