Which word adds information about a verb, adjective, or another adverb?

The correct answer is B, as an adverb is specifically designed to modify or provide additional information about verbs, adjectives, or other adverbs. For instance, in the sentence "She runs quickly," the adverb "quickly" modifies the verb "runs," giving us more detail about how she runs. Similarly, in a phrase like "very tall," the adverb "very" modifies the adjective "tall," enhancing the description of the height. This function of adverbs is essential in language as it allows for greater precision and nuance in expression. Other options, like nouns, adjectives, and conjunctions, serve different grammatical roles and do not fulfill the specific function of modifying verbs or adjectives. Nouns identify people, places, or things; adjectives describe nouns; and conjunctions connect clauses or sentences.
