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 Wrestlers is an oil study from life, depicting a black and a white wrestler grappling. Although at first glance the white wrestler appears to be dominant, the figures are in fact equally matched; this was unusual for the time, as it was a common belief in Britain in this period that black people were physically weaker than whites. Showing the subjects under bright light, the painting is a combination of intense juxtapositions between intimacy and violence, dark and light skin, and hard and soft surfaces. The black wrestler is naked; the white wrestler wears a loincloth, although it is possible that this was added after Etty's death. The intense light casts deep shadows, emphasising the curves and musculature of the wrestlers' bodies, as the skin of the two combatants is stretched and distorted under the pressure of the grapple. The figures are set against a dark green curtain and a brown wall, rather than in a wrestling ring.The identity of the wrestlers is not known. Alison Smith, Lead Curator of British Art to 1900 at Tate, speculates that the white figure may have been John Wilton of Somerset, who had possibly been the model for Little John in Daniel Maclise's 1839 Robin Hood and His Merry Men Entertaining Richard the Lionheart in Sherwood Forest. The figures glisten with sweat. Art historian Sarah Victoria Turner speculates that this is not simply for dramatic effect, but reflects the fact that after the Royal Academy's 1837 move to its new building in Trafalgar Square the studio used by the life class was a cramped and poorly ventilated room lit by gaslight, which when crowded with students and with the lights on could become extremely hot.
The Wrestlers is thought to have been painted in around 1840. It is likely that it was executed at the Royal Academy's life class; despite his senior status, Etty continued to attend there throughout his life. While students at the class usually worked from a single model, Etty would occasionally arrange for "a Treat", in which a group of models would be used to create an entire composition for the students to sketch (often arranged in poses derived from Old Master paintings). Painted on millboard, The Wrestlers was probably executed over the course of three evenings. On the first evening Etty would have drawn the models in chalk or charcoal and inked the outline; on the second evening the figures would have been painted in oil paint, and on the third evening a thin glaze would have been applied to the painting to which colour would then have been added.
A:
What is the name of the artist that would have drawn the oil study about two wrestlers grappling in three evenings?
