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: 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 solution: 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.

Problem: Passage: Gigolos in Europe are being terrorized by a serial killer. In Malibu, Deuce Bigalow's wife Kate has died from a shark attack, and Deuce is invited by his former pimp T.J. Hicks to Amsterdam. Deuce goes to take his mind off of Kate.
After T.J. shows Deuce his boat, or "float crib," the pair go to a coffee shop where they get high and bump into Heinz Hummer, a German gigolo. After leaving the coffee shop, Deuce finds Hummer dead in an alley, but thinks he is merely stoned and takes the dead gigolo to T.J.'s float crib; when T.J. gets back, he immediately realizes that Hummer is dead. T.J. plans to dump the body, but skeptical of Hummer's reputation of being well-endowed, unzips his pants and examines his genitalia and is caught by a tour boat.
Upon his release from the police station, Deuce finds T.J. at a restaurant and recalls that he saw the killer walking away from Hummer's body. Deuce says it was a woman, so they both figure it was a she-john, a former client of the murdered gigolo. T.J. convinces Deuce to find the killer by becoming a gigolo again, visiting the former clients and "rooting" out the killer. They attend a meeting of the Royal Order of European Man Whores, but fail to procure a list of the clients.
Solution: What are the full names of the characters who go to the meeting of the Royal Order of European Man Whores?
