TSA CBT Practice Test

The sentence "The window was broken by the wind" exemplifies a verb in passive voice because it highlights the action being done to the subject of the sentence, rather than the subject performing the action. In passive voice constructions, the subject receives the action, and the doer of the action can be introduced with the preposition "by." Here, "the window" is the subject that is acted upon, having been broken, and "the wind" is the agent that performs the action. In contrast, the other sentences depict active voice, where the subject performs the action. For instance, "The cat chased the mouse" shows the cat actively performing the action of chasing. Meanwhile, "She sings beautifully" and "They are playing soccer" both describe the subjects engaging in actions rather than being acted upon.
