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 addition to a produce market in Cornville, Arizona; Keenan, whose grandparents and great-uncle made wine in Northern Italy, owns Merkin Vineyards and Caduceus Cellars, based in the unincorporated area of Page Springs/Cornville, Arizona, southwest of Sedona, where he resides. While the winery is named after an ancient symbol for commerce (caduceus), the vineyard is named after a pubic wig (merkin). He is also a partner of Stronghold Vineyards, "an 80-acre site dedicated to producing affordable wines in the state", located in the small, unincorporated area known as Kansas Settlement in Sulfur Springs Valley, Arizona. Keenan's mother died in 2003, at the age of 59, due to complications from an aneurysm. Following her death, he scattered her ashes across one of his vineyards, and later named one of his wines after her, honoring her memory with his Cabernet Sauvignon "Nagual del Judith".In a statement released in April 2009, Keenan stated:
I am standing on a metaphorical plateau. The view from here suggests that I/we still have many mountains to negotiate. It has already been a long journey. But the successes and failures have been in balance. Which would suggest that I/we have chosen the correct path. I hold in my hands the evidence to support this statement. With tears in my eyes, I present to you the very first 100 percent Arizona Caduceus wine. Nagual del Judith, named after my late mother, Judith Marie.
I think there are a lot of misconceptions with some people that, all of a sudden, I was born when my first band came out. I actually had a life before that, and there were a lot of accomplishments. [The book] will kind of chronicle why it is I got to where I am, and why I got to where you knew about me.
Keenan's authorized biography, A Perfect Union of Contrary Things, was released on November 8, 2016.
