Which sentence uses the positive of an adverb?

The most basic modification an adverb performs is that found in a standard adverb phrase, or when an adverb modifies a verb to specify how an action was performed, either in manner, frequency, purpose, place or time. In the sentence, "She drove slowly," the adverb "slowly" modifies how she drove. Notice that the phrasing, "She slowly drove" would also be acceptable.
