Which of the following words is an example of an adverb silly, actually, lively ,or oily

An adverb is a word that modifies a verb, adjective, or another adverb. 
A verb is an action word (doesn't apply here)
An adjective is a describing word. Thing such as "Funny, Happy, Silly, Lively, and Oily are ADJECTIVES

Remember, an adverb must MODIFY an adjective, it can't BE an adjective.
The answer, using process of elimination, is ACTUALLY

For example:I didn't think he'd be like that, but he was actually funny!
Funny is the adjective, actually is the modifier, it further provides information for the word "funny"

Your answer is ACTUALLY
