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 input: 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 output: 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.
Q: Passage: The story is of the rise and fall of the Chicago gangster Al Capone and the control he exhibited over the city during the prohibition years.
On the evening of May 6, 1918, in Brooklyn, two police officers intercept a fur heist in an alleyway. Capone had tipped off the heist so that he could ambush the cops on arrival. As the officers arrest the men, Capone violently attacks them, and this results in a fight which ends when they throw Capone through a window, resulting in Capone having several scars on the left side of his face. The cops arrest Capone, but before they can interrogate him any further, the Police Lieutenant stops them and lets him loose. As he walks out of the station, Capone is picked up by Solly, an enforcer for racketeers Johnny Torrio and Frankie Yale. It is revealed that the two men in the fur heist were working for Johnny and Yale, and they decide to put Capone on Johnny's payroll.
A year later, on September 23, 1919, Johnny talks with his boss Big Jim Colosimo about Prohibition - a new law enforcing the eviction of alcohol. Johnny wants Big Jim to invest millions in bootlegging, but Colosimo declines. Johnny calls up Frankie and tells him to send Capone to Chicago. Johnny introduces Capone to co-workers, including Iris Crawford (Blakely). Johnny, despite his affection for his boss, is infuriated that he won't listen to his ideas, and so appoints Capone to murder Colosimo. The next morning, as Colosimo enters his restaurant and tries to call someone, Capone sneaks in and unloads a gun into the back of Colosimo's neck before watching him die.
