Answer 2

Answer:

then a mistake was made by me

Explanation:

When the subject of the sentence is the one doing the action expressed by the verb the sentence is in active voice. In the passive voice, the subject is the person or thing acted on or affected by the verb's action. The passive voice is made with a form of the verb be-such as is, was, or has been-and the past participle of the verb. The passive voice can be used when someone wants to emphasize an action that has taken place or when the agent of the action is unknown.

In the active voice, the person or thing that is a subject performs the action represented by the verb but in the passive voice, the subject; the person or thing acted on or affected by the action is represented by the verb.

Active voice: Lily knocked over the glass.

Passive voice: The glass was knocked over by Lily.
