Active and Passive Voice

• Active voice refers to the sentence where the subject is seen to carry out the action. In the passive voice, the action is given more importance.

• The sentence is given in the passive voice.

• The object has been omitted in the given sentence. Thus, I assume it to be 'they.' 'They' becomes the subject in the active voice.
