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.
One 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.
Solution is here: Who believes Fagin's gang make wallets and handkerchiefs?.
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.

Now, solve this: Passage: Soon after the US enters World War II, Steve Britt, a former World War I flying ace, arrives at Thunderbird Field, looking for a job as a civilian primary flight instructor. The base commander is an old friend, Lt. Col. "Mac" MacDonald, working with Squadron Leader Barrett (Reginald Denny, himself a World War I aerial observer), who is in charge of the Royal Air Force cadets at the base.
Steve says he wants the job because he is too old for combat and the war will be won by pilots trained on bases like Thunderbird, but it is soon clear that he chose this base because his former girlfriend, Kay Saunders, lives nearby with her grandfather, retired Colonel Cyrus "Gramps" Saunders, also a close friend of Steve's.
Steve immediately flies to their ranch and performs stunts over a water tank where Kay is bathing, blowing her robe away and then dropping her his flying coveralls. When he lands, she seems miffed, but responds to his passionate kiss of greeting. Kay is still very fond of him, but no longer deeply in love.
Steve is introduced to the new class of RAF cadets, including Peter Stackhouse, whose father Steve knew. Mac warns Steve to "wash them out fast" if cadets cannot meet the requirements. Peter flies clumsily and is sick from acrophobia. After three such failures, Steve tries to persuade Peter to transfer, but Peter is confident he can overcome what he calls his "conditional reflex", and asks for more time.
Solution:
Who picks a base because it is close to his girlfriend?
