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.
Example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Example solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Example explanation: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

Problem: 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.
Solution: What is the first name of the person that is noticed by Sasha?
