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: Wells Cathedral is an Anglican cathedral in Wells, Somerset, England, dedicated to St Andrew the Apostle and seat of the Bishop of Bath and Wells, whose throne or cathedra it holds as mother church of the diocese. Built between 1175 and 1490 to replace an earlier church on the site since 705, it is moderately sized for an English cathedral. Its broad west front and large central tower are dominant features in the city and countryside. It has been called "unquestionably one of the most beautiful" and "most poetic" of English cathedrals. Its Gothic architecture is mostly in the Early English style of the late 12th–early 13th centuries, lacking the Romanesque work that survives in many other cathedrals. Building began about 1175 at the east end with the choir. Historian John Harvey sees it as Europe's first truly Gothic structure, breaking with the last constraints of Romanesque. The stonework of its pointed arcades and fluted piers bears pronounced mouldings and carved capitals in a foliate, "stiff leaf" style. Its Early English front with 300 sculpted figures, is described as a "supreme triumph of the combined plastic arts in England". The east end retains a rare amount of ancient stained glass. Unlike many cathedrals of monastic foundation, Wells has many surviving secular buildings linked to its chapter of secular canons, including the Bishop's Palace and the 15th-century residential Vicars' Close. The cathedral is a Grade I listed building.
