Question

In which sentence does the adverb "downhill" function as an adjective?

• A. The route is downhill from here to the finish line.
• B. His business was going downhill.
• C. He ran downhill till he reached the inn.
• D. Their marriage went downhill after the death of their child.

Answer 1

The correct option is A The route is downhill from here to the finish line.

An adverb is a word that describes or modifies a verb. In option D, "downhill" modifies the verb "went", making it an adverb. Thus, option D is incorrect. Similarly, in both B and C, "downhill" works as an adverb that modifies the verbs "going" and "ran", respectively, making both of these options incorrect.

An adjective is word that modifies or gives additional information about a noun. In option A, "downhill" describes the noun, "route". It describes what kind of route it is. Option A, therefore, works as an adjective, making it the correct option.
