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: World War I veteran Waldo Pepper feels he has missed out on the glory of aerial combat after being made a flight instructor. After the war, Waldo had taken up barnstorming to make a living. He soon tangles with rival barnstormer (and fellow war veteran) Axel Olsson.
Antagonistic at first, Waldo and Axel become partners and try out various stunts. One of these stunts, a car-to-aircraft transfer, goes wrong and Waldo is nearly killed after Axel is unable to climb high enough to clear a barn, slamming Waldo into it.  Waldo then goes home to Kansas to be with on-again, off-again girlfriend Maude and her family. Maude, however, is not happy to see Waldo at first; because every time he returns from a barnstorming tour of the country, he is injured in some way. Eventually, however, they make up and become lovers once again. Meanwhile, Maude's brother Ezra, a long-time friend of Waldo's since boyhood, promises to build Waldo a high-performance monoplane as soon as he is well enough to fly it. Waldo's goal is to become the first pilot in history to successfully perform an outside loop, and Ezra feels Waldo can do it with the monoplane.
Solution: What is the full name of the person who tangles with a rival barnstormer?
