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: The village symbol is the Briarcliff Rose, a more brightly colored offshoot of the American Beauty rose. Since 2006, the Briarcliff Rose has been used on village street signs. The Briarcliff Manor Garden Club, which also uses the Briarcliff rose as their symbol, was established in 1956. One of its primary functions is in planting, maintaining, and improving public gardens and grounds.Briarcliff Manor has groups in several Scouting organizations, including Cub Scout Pack 6 and Boy Scout Troop 18. Pack 6 became the first Cub Scout pack in the village at its establishment in 1968; by 2002 it had over 70 cubs in 12 dens. The village's first Boy Scout troop was Troop 1 Briarcliff, founded before 1919. Sources cite Bill Buffman as the first Scoutmaster and John Hersey as the troop's first Eagle Scout. The first Girl Scout troop in the village was founded in 1917 by Louise Miller and Mrs. Alfred Jones, and the first Brownie troop was founded in 1929.The Briarcliff Manor Community Bonfire is a winter holiday event at Law Park, hosted by the village and the Briarcliff Friends of the Arts, involving live music (primarily seasonal and holiday songs), refreshments, and craft projects for children. Another annual community event is the Memorial Day parade, a tradition in Briarcliff Manor for more than fifty years. Before the parade begins, the Municipal Building's bell is rung to commemorate firefighters who have died in the previous year; the parade ends at the village's war memorial in Law Park, where wreaths are laid on the monument. The holiday has been celebrated in the village since the early 1900s, though initially involving large family picnics, with parades reserved for the Fourth of July.
