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: Singing cowboy and rodeo star Gene Autry inherits half interest of a ranch and mining property from his late foster father, Henry "Dad" Erwin. The other half is left to Dad's niece, Barbara Erwin who arrives at the ranch from the East with her friend, Kitty Callahan. The will stipulates that each has an "undivided interest" in the inheritance—that each owns half of everything—and that nothing can be sold off without the approval of the other. In desperate need of money, Barbara expresses her desire to sell the mine as quickly as possible. Gene, however, wants to continue Dad's work on the mine, which employs Mexican rancheros whose land was ruined by dust storms. He explains that although the profits are currently put back into operations, eventually the mine will provide her with an income, and that without the mine, the rancheros will not survive.
With not enough money to return East, Barbara and Kitty decide to stay, and plan to use their feminine wiles on Gene and his sidekick, Frog Millhouse, to get gene to change his mind about selling. Meanwhile, Gene assures the rancheros that the mine will not be sold and that he will continue Dad Erwin's work. After her sweet-talking fails to win Gene over to her side, Barbara hires attorneys Arnold and Fry to sell the mine for her, giving them the power of attorney. Unknown to Barbara, the unscrupulous lawyers have been trying for years to gain control of the mine. They order their henchman Tommick to get rid of Gene. Tommick and his gang ride out to the mine and initiate a gunfight, but Gene and the rancheros are able to defend themselves.
A:
