Which revision correctly converts the passive voice sentence about the broken window into active voice?

The correct choice effectively transforms a passive voice sentence into an active voice construction. In passive voice, the subject of the sentence is acted upon, creating a disconnect between the doer (the agent) and the action. In the original passive sentence, the window is the subject but does not perform the action of breaking.

By selecting the revision that states "The speeding baseball broke the window by crashing into it," the subject (the speeding baseball) becomes the agent actively performing the action (breaking the window). This change clarifies who is responsible for the action and enhances the sentence's directness and engagement.

This choice also maintains the detailed context of how the action occurred, allowing for a vivid understanding of the event. Overall, it successfully conveys the intended meaning while following the structure and clarity of active voice.
