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: 18-year-old Joy starts her catalogue of bad choices by running away from home with Tom. They marry and have a son, Johnny. When Tom, a thief who mentally and physically abuses Joy, is jailed for four years after attempting a big robbery, she is left on her own with their son.
After briefly sharing a room with her Aunt Emm, an aging prostitute, she moves in with Dave, one of Tom's former associates.

Intending to be faithful, Joy writes to him constantly, moves back with Aunt Emm, and initiates divorce proceedings against Tom. She takes a job as a barmaid, starts modelling for a seedy photographers' club and drifts into promiscuity.

After a frantic search, she finds him on a demolition site. Realising how much Johnny means to her, she accepts the need of compromise and stays with Tom, but she continues to dream of a distant future with Dave.
