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.

Input: Consider Input: Passage: The Annunciation draws heavily on van der Weyden's 1430s Louvre Annunciation, his c. 1455  Saint Columba altarpiece, and the Clugny Annunciation (c. 1465–75), which is attributed to either van der Weyden or Memling. Memling almost certainly was apprenticed to van der Weyden in Brussels until setting up his own workshop in Bruges sometime after 1465. Memling's Annunciation is more innovative, with motifs such as the attendant angels that were absent in the earlier paintings. According to Till-Holger Borchert, not only was Memling familiar with van der Weyden's motifs and compositions, but he might have assisted with the underdrawing in van der Weyden's workshop. The shutters on the right are copied from the Louvre panel, the knotted curtain appears in the Columba triptych's "Annunciation".A sense of movement is conveyed throughout. The trailing edges of Gabriel's garment fall outside the pictorial space, indicating his arrival. The Virgin's "serpentine" pose, with attendant angels supporting her, adds to the sense of flow. Memling's use of color achieves a startling effect. The traditional rays of light are replaced with light color indicators; the white clothes rendered in "icy" blue, the angel to the right in yellow patches seems "bleached by light", the left-hand angel appears to be steeped in shadow, dressed in clothes of lavender and bearing deep green wings. The effect is iridescent, according to Blum, who writes, "this shimmering surface gives [the figures] an unearthly quality, separating them from the more believable world of the bedchamber." The effect deviates from the pure naturalism and realism which typifies Early Netherlandish art, causing a "startling" juxtaposition, an effect that is "unsteadying" and contradictory.

Output: What is the name of the person who might have assisted with the underdrawing in Van der Weyden's workshop?


Input: Consider Input: Passage: Fifteen-year-old Ellis Whitman is leaving his home in Tucson, Arizona, for his freshman year at Gates Academy, an East Coast prep school. He leaves behind Wendy, his flaky, New Age mother and Goat Man, a weed-smoking goat trekker and botanist. Goat Man is the only real father  Ellis has ever known, since his biological father, Frank, left when he was a baby.
Upon arriving Gates Academy, Ellis befriends his roommate Barney Cannel, a cross-country runner, and Rosenberg, who usually does not get anything higher than a C in his classes, but is smart enough to sneak in marijuana. Ellis also takes an interest in Minnie, a local girl who works in the school library; his friends often refer to her as a prostitute, according to rumors. Meanwhile, Goat Man and Wendy have been incommunicado, which Barney points out often. On a phone call, Ellis discovers that his mother has a new boyfriend named Bennet, who is rude and disrespectful.
One day, Ellis receives a letter in the mail from his long-estranged father from Washington, DC, requesting for Ellis to spend Thanksgiving dinner with him. Ellis decides to fly to Washington with Barney, who is also having Thanksgiving with his mother there. Ellis finally meets his father and his father's pregnant and kind-hearted wife, Judy. One night, Ellis gets a call from Barney telling him that he is in possession of marijuana. Ellis sneaks out for the night, but Frank finds out that he left. On the way back from his flight from DC, Barney and Ellis get drunk and fight with each other in their dorm room, resulting in a dent in the wall which costs Wendy $700 and Ellis to end up in the school hospital. Afterwards, Ellis begins to get closer to Minnie.

Output: Who has a flaky New Age mother?


Input: Consider Input: 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.
Output: The secondary art market, meanwhile, was returning six-figure sums for whose works at auction?
