Question

She switched on the light and left the door open. Voice change

Answer 1

The light was switched on by her and left the door open.

Answer 2

In a sentence with an active voice, the subject performs the action which is denoted by the verb. In other words, the subject is the doer of the action. Whereas in a passive voice, the subject is not active but by the verb is acted upon.

Passive voice is the voice used to show an interest in the object or person who experienced the action rather upon the action performer. In passive voice, a subject is an important thing.

The sentence when written in passive voice, it would be written as:

The light was switched on by her and left the door open.
