COMPOUND SUBJECTS USUALLY TAKE PLURAL VERBS
The subject is what the sentence or clause is about. The subject is a noun or pronoun and usually performs that action of the verb.

The business presentation was presented to the committee on Monday. (This sentence is in the passive voice, so the doer is not the subject.)
When a sentence or clause has two or more subjects, they are called a compound subject.
