TSA CBT Practice Test

The correct choice is "suddenly" because it is a word that modifies verbs, adjectives, or other adverbs, which is the defining characteristic of adverbs. In this case, "suddenly" describes the manner in which an action occurs, often indicating that something happens unexpectedly or without warning. The other words listed function differently in a sentence. "Large" is an adjective used to describe the size of a noun. "Beautiful" is also an adjective, used to describe the aesthetic quality of a noun. "Yours" serves as a possessive pronoun, indicating ownership, thus it does not modify other parts of speech in the way that adverbs do.
