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.

One morning on his way to work, Peter goes on the London Underground train and spots what seems to be a murder being committed on at the open window of a building overlooking the tracks. Deciding to investigate this "crime" Peter and a policeman arrive at the residence. There they find out that the couple were in fact rehearsing an illusion. Zoltini is a bad tempered magician and his wife Vivienne is his assistant. The suspicious magician becomes sure that his wife is having an affair with Peter - every time he sees her with the handsome stranger. On another night Zoltini and Vivienne have an argument on the backstage - leading to him slapping her in the face. As a result, Vivienne leaves (while her husband performs on stage) and takes a taxi with Peter up to his crane. Furious with Vivienne for leaving during the 'vanishing women' sequence of their performance, Zoltini looks for his wife while Pat has been sacked from the hotel for not paying attention to her job.
