Detailed Instructions: 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.
Q: Passage: A number of artists traditionally associated with the movement had origins that were neither Dutch nor Flemish in the modern sense. Van der Weyden was born Roger de la Pasture in Tournai. The German Hans Memling and the Estonian Michael Sittow both worked in the Netherlands in a fully Netherlandish style. Simon Marmion is often regarded as an Early Netherlandish painter because he came from Amiens, an area intermittently ruled by the Burgundian court between 1435 and 1471. The Burgundian duchy was at its peak influence, and the innovations made by the Netherlandish painters were soon recognised across the continent. By the time of van Eyck's death, his paintings were sought by wealthy patrons across Europe. Copies of his works were widely circulated, a fact that greatly contributed to the spread of the Netherlandish style to central and southern Europe. Central European art was then under the dual influence of innovations from Italy and from the north. Often the exchange of ideas between the Low Countries and Italy led to patronage from nobility such as Matthias Corvinus, King of Hungary, who commissioned manuscripts from both traditions.The first generation were literate, well educated and mostly from middle-class backgrounds. Van Eyck and van der Weyden were both highly placed in the Burgundian court, with van Eyck in particular assuming roles for which an ability to read Latin was necessary; inscriptions found on his panels indicate that he had a good knowledge of both Latin and Greek. A number of artists were financially successful and much sought-after in the Low Countries and by patrons across Europe. Many artists, including David and Bouts, could afford to donate large works to the churches, monasteries and convents of their choosing. Van Eyck was a valet de chambre at the Burgundian court and had easy access to Philip the Good. Van der Weyden was a prudent investor in stocks and property; Bouts was commercially minded and married the heiress Catherine "Mettengelde" ("with the money"). Vrancke van der Stockt invested in land.
