Task: Question Generation
Input (English): Passage: The film follows the personal relationship between a father, Arkady Shapira, his terminally ill wife Irina, and his two sons, Joshua and Reuben (Roth and Furlong). Joshua, the elder, is a hit-man for the Jewish-Russian mafia in Brooklyn and estranged from his family. After finishing a contract killing, Joshua is ordered to kill an Iranian jeweler in Brighton Beach, which Joshua reluctantly accepts. Joshua stands outside his family's apartment, where he is spotted by one of his old friends Sasha, who tells Joshua's brother Reuben the next day. Reuben goes to the hotel where Joshua is staying to see him. Joshua asks Reuben how he knew he was in Brighton, and they make plans to meet again the next day.
Joshua waits near the boardwalk where Sasha is and intimidates him to tell who else knows about Joshua being in Brighton. Sasha brings Joshua to the car repair
stand where Viktor and Yuri are. Joshua says they will help him find the Iranian jeweler and when they refuse, Joshua threatens them.
After things go sour, Joshua executes a man at a phone booth to prevent being found out in Brighton, which angers the neighborhood boss Boris Volkoff. Joshua starts dating his ex-girlfriend Alla. Alla asks Reuben if he has seen Joshua anywhere and the three go together to see a movie. Eventually Reuben takes Joshua home to see his parents again, but Arkady denounces him as a murderer and kicks him out.
Joshua uses information about his father's affair to see his dying mother. After reminiscing about the past, Joshua's mother asks him to go to his grandmother's birthday party, which Joshua agrees to.
Output (English): Who refuses to help Joshua find the Iranian jeweler?
