You will be given a definition of a task first, then some input of the task.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: A truce between two rival gangs, the Tigers and the JPs, come to an end when after a day at school, the Tigers are attacked by members of the JPs, led by Spider. When Tigers leader Max warns Spider about the truce, Spider informs Max it is his gang and they want the streets back. Max gets help in Charlie, who is a martial arts expert but in the melee, Tigers member Spud is stabbed by Spider. Later that day, the JP leader Priest has been released from prison alongside Tok, a mute prisoner who saved Priest and has become his most trusted companion. Upon returning to the hangout, Priest has learned that Spider had broken the truce. Angry, Priest and Spider settle the score with Priest winning and regaining full leadership of the gang.
Meanwhile, reeling from the loss of Spud, Max finds it hard to work at the local warehouse. He is good friends with the manager, Troy, who tries to help him cope with his problem. Max tells Troy of an upcoming school dance and wants to introduce him to his girlfriend's friend. Max's girlfriend, Marie, works at a clothing store with Julie. Marie invites Julie to the dance perhaps in an effort to introduce her to Troy. That night at the dance, Charlie and Troy meet when they both ask Julie to dance. However, the celebration is interrupted by the arrivals of the JPs. When Julie sees Priest, she is in complete shock as it is revealed that Priest is Julie's ex-boyfriend, who plans to get her back at any cost. A fight breaks out and Charlie attempts to help, but is outmatched by Tok, who is a master martial artist himself. Troy and Charlie soon become friends and Charlie decides that Troy may have the potential to be able to defend himself.
Output:
Who is good friends with the manager?
