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: Gloria, a downtrodden housewife, lives with her husband Antonio, mother-in-law and two sons in a small, shabby and overcrowded  apartment located by the Madrid motorway. Besides taking care of her home and family, Gloria also works as a cleaning lady to make ends meet and takes amphetamines to keep going. Her marriage to Antonio, a male chauvinist taxi driver, is on the rocks. Fifteen years earlier, in Germany, Antonio worked as a driver for Ingrid Muller, a German singer with whom he had a brief affair. His only mementos of their liaison are a signed photograph and a tape of her song Nur nicht aus Liebe Weinen which he constantly plays and which Gloria detests.
Antonio's services for Ingrid involved copying letters that she had allegedly received from Hitler himself. In his taxi Antonio meets the writer Lucas and Antonio casually mentions this fact to Lucas, who suggests that they forge Hitler's diaries for big profit.
There is also a book of Ingrid's memoirs written by a friend which contains letters from Hitler which Antonio helped forge. Antonio is trying to teach the art of forgery to one of his sons, as this talent will be his only inheritance. The younger son, Miguel, who is twelve, sleeps around with older men. When Gloria confronts Miguel, telling him she knows he has been sleeping with older men (including his friend's father), Miguel responds: "I'm the master of my own body." Gloria's eldest son, Toni, who is fourteen, wants to become a farmer and is saving up enough money to buy a farm by peddling heroin. The grandmother, who is addicted to soft drinks, shares the same dream of returning to her native village. Gloria's friends are her two neighbors: Cristal and Juani. Cristal is a prostitute with a heart of gold. Juani, is a bitter woman obsessed with cleanliness and vulgar ornaments, her daughter, Vanesa, has  telekinetic powers, which she uses to destroy their apartment.
