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


question:
Passage: By the 15th century the reach and influence of the Burgundian princes meant that the Low Countries' merchant and banker classes were in the ascendancy. The early to mid-century saw great rises in international trade and domestic wealth, leading to an enormous increase in the demand for art. Artists from the area attracted patronage from the Baltic coast, the north German and Polish regions, the Iberian Peninsula, Italy and the powerful families of England and Scotland. At first, masters had acted as their own dealers, attending fairs where they could also buy frames, panels and pigments. The mid-century saw the development of art dealership as a profession; the activity became purely commercially driven, dominated by the mercantile class.
Burgundian rule created a large class of courtiers and functionaries. Some gained enormous power and commissioned paintings to display their wealth and influence. Civic leaders also commissioned works from major artists, such as Bouts' Justice for Emperor Otto III, van der Weyden's The Justice of Trajan and Herkinbald and David's Justice of Cambyses. Civic commissions were less common and were not as lucrative, but they brought notice to and increased a painter's reputation, as with Memling, whose St John Altarpiece for Bruges' Sint-Janshospitaal brought him additional civic commissions.Wealthy foreign patronage and the development of international trade afforded the established masters the chance to build up workshops with assistants.  Although first-rank painters such as Petrus Christus and Hans Memling found patrons among the local nobility, they catered specifically to the large foreign population in Bruges. Painters not only exported goods but also themselves; foreign princes and nobility, striving to emulate the opulence of the Burgundian court, hired painters away from Bruges.
answer:
What were the name of three paintings civic leaders commissioned from major artists?


question:
Passage: Laura Reynolds is a free-spirited, unwed single mother living with her young son Danny in an isolated beach house in Big Sur, California.  She makes a modest living as an artist and home-schools her son out of concern that he will be compelled to follow stifling conventional social norms in a regular school.  Danny has gotten into some trouble with the law through two minor incidents, which are in his mother's eyes innocent expressions of his natural curiosity and conscience rather than delinquency.  Now with a third incident a judge orders her to send the boy to an Episcopal boarding school where Dr. Edward Hewitt is headmaster, and his wife Claire teaches. Edward and Claire are happily married with two student sons, but their life has become routine and their youthful idealism has been tamed by the need to raise funds for the school and please wealthy benefactors.
At an initial interview, there is a momentary immediate attraction between Laura and Edward, but this quickly turns into tension brought on by their greatly differing world views and Laura's dislike of religion.  Finally she storms out.  She attempts to flee the area with Danny but the police quickly catch them and take the boy away to the school.  He initially has trouble fitting in because his mother's home schooling has placed him far in advance of boys his age in many subjects; the standard course of instruction at the school leaves him restless and bored.  At Claire's suggestion, Edward visits Danny's mother to learn more about his upbringing.
answer:
What's the full name of the person the headmaster go to visit to learn more about Danny?
