Question

What is a verb?
a. A word or group of words used to express surprise or sudden feeling.
b. A word that says what a noun does
c. A word used as the name of a person, place, or thing
d. A word that modifies, or describes, a noun or pronoun

Answer 1

a verb is a word used to describe an action or a state. Based on that, I'd say it looks like it's B. It can't be C, because C describes a noun. It doesn't look like A, either. An adverb modifies or describes a noun or pronoun, so I'd get rid of D, too. That only leaves B

Answer 2

a word used to describe an action, state, or occurrence, and forming the main part of the predicate of a sentence, such as hear, become, happen.
