Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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: Who believes Fagin's gang make wallets and handkerchiefs?.
Reason: 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 instance: Passage: a sample of Oliver's hair contained a very high level of copper, nearly 8 times normal. The debilitating effects of high copper levels, which are associated with some mental illnesses, may have been exacerbated by an imbalance created by low zinc levels in her diet, which was devoid of red meat.Just before her death, Oliver had been shortlisted for the 2006 Clemenger Contemporary Art Award. In the year following, Oliver was amongst 60 artists profiled in Sonia Payes' book Untitled: Portraits of Australian Artists, while in 2008 her final works were included in the Adelaide Biennale of Australian Art. The secondary art market, meanwhile, was returning six-figure sums for her works at auction; in 2007 a record for Oliver's work was set when Skein (2004) went under the hammer for $192,000. By 2010, Sydney Biennale chairman Luca Belgiorno-Nettis was reported to have paid $300,000 for one of Oliver's sculptures, titled Tracery. In 2011, Sydney's College of Fine Arts announced that its new sculpture studio would be named after Oliver. In late 2017 Hannah Fink's book Bronwyn Oliver: Strange Things was launched by Kip Williams at Carthona.Works by Oliver are held in most major Australian art collections, including the National Gallery of Australia, the Art Gallery of New South Wales, the National Gallery of Victoria, Queensland Art Gallery, the Art Gallery of South Australia, the Auckland Art Gallery, the Tasmanian Museum and Art Gallery, Wollongong City Gallery, Orange Regional Gallery, and the Australian government's collection Artbank. The first "comprehensive survey of 50 key works, from the mid-1980s to the final solo exhibition in 2006" was held in Tarrawarra Museum of Art in Healesville, Victoria from 19 November 2016 to 5 February 2017.
