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: In the five years since the previous film, Fin has moved to a farm in Kansas named "April's Acres," where he lives with his mother Raye and young son Gil. April is believed dead after being crushed by the wreckage of the space shuttle. Tech mogul Aston Reynolds (based on Tesla, Inc. co-founder and SpaceX founder Elon Musk) has developed a new type of high-speed space travel with his company Astro-X (a play on SpaceX), which was used to save Fin's father, Colonel Gilbert Shepard, from the moon. Astro-X has also developed a technology that is capable of using radio waves to diffuse tornadoes, leading to the end of the sharknado phenomenon.
Fin travels to Molong with his cousin Gemini to meet up with his son Matt, who has returned from deployment in Iraq. Meanwhile, Reynolds has built and is opening a shark-themed hotel featuring a giant tank of sharks. While Matt and his fiancée, Gabrielle, marry and skydive from a plane, a sandstorm tornado develops that cannot be diffused by Astro-X. The tornado absorbs the water and sharks from Reynolds' hotel, creating the first sharknado in five years. The streets of Las Vegas flood, but Fin, Gemini, Gabrielle, and Matt work together to survive the storm until it heads back out into the desert.
