Which part of speech modifies verbs, adjectives, or other adverbs?

• A. Adjective
• B. Conjunction
• C. Adverb
• D. Interjection

Answer: (C)

The correct answer is "C," which is adverb. An adverb is a part of speech that modifies verbs, adjectives, or other adverbs, providing more information about how, when, where, or to what extent something occurs. For example, in the sentence "She runs quickly," the adverb "quickly" modifies the verb "runs" by describing the manner of the action. Similarly, in "He is very tall," the adverb "very" modifies the adjective "tall," intensifying its meaning.

In contrast, adjectives modify nouns by providing descriptive details, while conjunctions connect words, phrases, or clauses. Interjections are words or phrases expressing strong emotion or surprise, and they stand apart from the structural functions of verbs, adjectives, or other adverbs. Thus, adverbs play the specific role of enhancing or clarifying the meaning of verbs, adjectives, or other adverbs in a sentence.
