Question

Which of the following sentence(s) contains an adverb?

• A. She can run very fast.
• B. She was a friendly person.
• C. I was late.
• D. She is a good pianist.

Answer 1

The correct option is A She can run very fast.

Adjectives are words that modify or describe nouns.

Not all words that end with "-ly" are adverbs. In option B, "friendly" describes or modifies the noun "person". It tells us what kind of person the subject is. Thus, option B is incorrect since "friendly" is an adjective. In option C, "late" is also an adjective since it gives information or modifies the subject noun "I". Thus, C is incorrect since it is an adjective. In D, "good" describes what kind of pianist the subject is. Thus, it modifies the noun "pianist". Option D, then, is an adjective which makes it the incorrect option.

An adverb usually modifies a verb and sometimes, another adverb or adjective. In option A, "fast" is an adverb as it describes the action or verb "run". "Very" is also an adverb since it describes the intensity of the adverb "fast". Thus, option A is correct.
