The following sentence may contain a grammar or usage error. Parts of the sentence are underlined. Choose the underlined part of
the sentence that contains an error. If there is no error in the sentence, choose "No error." During the chaotic and frenzied celebrations on New Year's Eve, Jason walked calm and cool through town.
Since the speaker is trying to modify the verb "walked" in order to indicate the manner in which it was done, the right thing to do would be using adverbs. "Calm and cool" are adjectives and should, as such, modify nouns. If, however, we transform them into adverbs by ending the suffix -ly (calmy and coolly), the sentence will be correct.
During the chaotic and frenzied celebrations on New Year's Eve, Jason walked calmly and coolly through town.
