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.

Let me give you an 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.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: 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.

Passage: The film opens with two small-time crooks Tommy Uva and Rosie DeToma getting high and robbing a florist on Valentine's Day. Tommy holds up the cashier with a pistol while Rosie waited in the car she inherited from her father. Tommy is arrested and sent to prison for 18 months. In the meantime, Rosie gets a job at a debt collection agency run by Dave Lovell, who went to jail for bilking major companies out of $800,000 through fraudulent invoices. Lovell reformed his life and mainly hires ex-cons at his firm. He is happy to give Tommy a job and a second chance. Tommy is restless and instead of following the call script, he often counsels people on how to defraud Lovell's company.
When Tommy sees some mafiosos in his neighborhood, he grows enraged. He calls them fat old guys living off their reputation, and he resents the way the mafia treated his father. Over the course of the film, it is revealed that Tommy's father started his shop with a mafia loan, and he suffered frequent beatings when he was late with payments. Tommy's mother and brother still run the shop, but his mother blames Tommy's criminal activity for breaking her husband's heart and leading to his death. Whereas, Tommy blames his father's death completely on the humiliation he suffered at the hands of the mafia.
Tommy skips work one day to attend the trial of John Gotti. He watches Sammy the Bull's testimony, and he perks up when Sammy explains that no guns are allowed in mafia social clubs. He cases one of the clubs that Sammy mentioned, and then he pitches the idea to rob the club to Rosie. He explains that it will be safe since no one will have a gun, and that the mafia would never call the cops to report the crime. He gets an Uzi, which he does not know how to use. Rosie reluctantly shows him how to load it, and agrees to the plan.
Answer:
Who does Tommy call names?
