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: Sergeant Joe Gavilan is a financially strapped homicide detective with the Hollywood Division of the LAPD. He has been moonlighting as a real estate agent for seven years. His current partner is K. C. Calden, a much younger detective who teaches yoga on the side and wants to be an actor. The partners are investigating the murders of the four members of rap group "H2OClick", who were gunned down in a nightclub by two unidentified assailants. The detectives discover there was a witness who fled, and they work to track him down. They are distracted, failing to bond as partners, as Gavilan has to deal with a looming real estate deal that may be the key to getting out of debt, while Calden further pursues his dreams of acting by trying to be scouted by talent agents.
Meanwhile, the manager of H2OClick, Antoine Sartain, has his head of security eliminate the two hitmen, who he had hired to kill H2OClick and, earlier a rapper named Klepto that Sartain also managed.
Gavilan and Calden believe the murders are gang-related, but when Calden happens to see the bodies of the hitmen at the morgue, they conclude that the murders were orchestrated. The detectives also notice similarities that tie the H2OClick and Klepto homicides together. Gavilan learns from an undercover officer that the songwriter for H2OClick, a man named K-Roc, has gone missing, leading Gavilan to believe he is their murder witness. They struggle to track down K-Roc until they finally learn his real name, Oliver Robideaux, the son of former Motown singer Olivia Robideaux.
