Provide the answers to an adverbs test, including explanations for each.

here are the answers to the Adverbs test:

1. C) quickly The word needed here is an adverb to modify the verb "completed," describing how she completed the task. "Quickly" is the adverb form of "quick."

2. A) clearly The word needed is an adverb to modify the verb "spoke," describing how he spoke. "Clearly" is the adverb form of "clear."

3. B) earlier The word "than" indicates a comparison. "Earlier" is the comparative form of the adverb "early," comparing the train's arrival time to the expected time.

4. B) more beautifully The word "than" indicates a comparison. "Beautifully" is an adverb modifying the verb "sings." To compare how two people sing, we use the comparative form of the adverb, which for "beautifully" is "more beautifully."

5. C) hard The word "hard" can function as both an adjective and an adverb. In this sentence, it modifies the verb "works," describing how he works. "Hardly" is also an adverb, but it means "almost not" and would change the meaning of the sentence significantly (e.g., "He hardly works" means he rarely works).
