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: Frank Moses, retired black-ops CIA agent, lives alone in Cleveland, Ohio. Lonely, Frank creates opportunities to talk to Sarah Ross, a worker at the General Services Administration's pension office in Kansas City, Missouri, by tearing up his pension checks and calling to say they haven't arrived.
One night, an assassination squad raids Frank's house and attempts to kill him but he easily wipes them out. Knowing they will have tapped his phone, he believes Sarah will be targeted. In Kansas City Sarah refuses to go with him so he kidnaps her. Meanwhile CIA agent William Cooper is assigned by his boss Cynthia Wilkes (Pidgeon) to hunt down and kill Frank.
To find out who is targeting him Frank tracks down his old associates for help. He goes to New Orleans, Louisiana, and visits his CIA mentor Joe Matheson, who tells him the same hit squad murdered a New York Times reporter. An agent posing as a police officer tries to abduct Sarah but Frank returns in time. Cooper chases them but Frank tricks the police into arresting Cooper and escapes with Sarah. The two head to New York City and find clues left by the reporter which lead them to a hit list.
They find Marvin Boggs, another old associate and a paranoid conspiracy theorist, who tells them the people on the list, including Frank and Marvin, are connected to a secret 1981 mission in Guatemala. A pilot on the list, Gabriel Singer, tells them the mission involved extracting a person from a Guatemalan village. Singer is shot by a helicopter-borne machine-gunner and the team escapes as Cooper closes in.
