Special Agent Entrance Practice Exam

The correct answer showcases a verb demonstrating a clear action: "writes." In this sentence, the subject "She" is actively performing the task of writing a letter, which is a direct, observable action.

In contrast, the first option describes a state of being rather than an action. "Is" functions as a linking verb, connecting the subject "The grass" to its description, "green." The second option puts emphasis on an emotional state with the verb "felt," which, while it does imply an action, primarily indicates a state of feeling rather than a physical action being carried out. "Writes" stands out because it presents a tangible action that can be visualized and quantified. Thus, it effectively fulfills the requirement of being an action verb.
