Answer 2

Answer: The right answer is "hard."

Explanation: Just to elaborate a little on the answer, it can also be said that an adverb (from the Latin adverbium, "near the verb") is a word or group of words that can modify not only the meaning of a verb, but also of an adjective or of an entire sentence. In this example, it features the form of an adjective - hard.
