Which sentence uses passive voice?
mark's torn pants and sweatshirt made his mother sigh.
the snow from last week's storm melted when temperatures rose.
the long-awaited victory was earned by every player on the team.
before she left for the airport, mrs. kelly kissed her cat and dog.

The correct answer is: The long-awaited victory was earned by every player on the team.

Indeed, a passive construction includes an object and a subject: the agent, who performs the action, and the patient, who receives the action or its consequences. The auxiliary verbs be or get are used to create a passive voice along with the past participle of the central verb.

In this phrase the agent and object is “the team” who won the victory, and the said victory is the patient or subject of the sentence.
