12) If a sentence's subject performs an action, then the verb's voice is A active B inactive C aggressive D passive

A active

When the subject of a sentence is the one performing the action denoted by the verb, the verb is said to be in the active voice. This means the subject is active, doing the action, rather than receiving it.

To compare, when the subject of the sentence is receiving the action, the verb is in the passive voice. In a passive voice sentence, the object of the action often appears at the beginning of the sentence and appears to be the one doing the action, though it's actually the one receiving it. The real performer of the action typically comes after the verb, often introduced by the preposition "by." For example, in the active sentence "The cat chased the mouse," the subject "the cat" performs the action of chasing. In the passive sentence "The mouse was chased by the cat," the subject "the mouse" receives the action. "Inactive" and "aggressive" are not grammatically recognized voices of verbs. The concept of verb voice is important for students because it helps in writing sentences that are clear and precise. By choosing between active and passive voice, students can control the emphasis and clarity of their statements.
