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: Astronomer Cyrus Layton is working late one night on his new airplane design in his observatory. He witnesses what he believes is a meteorite landing in the far distance. He contacts his niece Sheila and asks her to bring Craig Foster to the observatory to help analyze his discovery; he then sets out to search for the meteorite crater. Layton instead discovers a crashed spaceship; the ship's pilot emerges and explains that he is from the planet Mars.
Mistakenly thinking the alien is friendly, Layton takes him back to the observatory. Once there the Martian, calling himself "The Purple Monster," wishes to see Layton's designs for the new airplane/spaceship. He proudly shows the alien his designs until the alien explains that he is now stealing them, to build a spaceship for himself to fly back to Mars, where a fleet of the ships will then be used invade the Earth. When Dr. Layton objects, the Martian murders him with a weapon that emits a "carbo-oxide" gas, which kills instantly. The alien then transforms into a ghost and takes over Dr Layton's body. Doing so fools the astronomer's niece Sheila and criminologist Craig Foster, both of whom work with Dr. Layton's foundation, which is responsible for commissioning the spaceship project.
Inhabiting Dr. Layton allows the Martian to witness the unrelated theft of the plans by a gangster named Garrett. The Martian convinces Garrett and his gang to aid in the invasion plot. With the criminals' help the alien begins building the spaceship. Eventually, however, the Martian's efforts at pretending to be Dr Layton fall apart, and Foster and Sheila realize what is happening. A series of action scenes show the pair trying to figure out and stop whatever the alien is doing on Earth. Craig and Sheila constantly battle the Purple Monster's henchmen, who use mind-control poisons, carjackings, and even a booby-trapped vacant lot to dispose of Craig and Sheila.
A:
Who is related to the man that is killed by "carbo-oxide"?
