This document discusses the difference between active and passive voice in writing. It defines voice as a characteristic of verbs that indicates the relationship between the verb's action and its subject. Active voice verbs show the subject performing the action, while passive voice verbs show the subject receiving the action. Although both are grammatically correct, active voice is usually clearer and more direct for academic and business writing. The document provides examples of active and passive voice constructions and a quiz for readers to practice identifying them.
