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.

[EX Q]: 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.
[EX A]: What were the name of three paintings civic leaders commissioned from major artists?

[EX Q]: Passage: The first eruptions of Nevado del Ruiz occurred about 1.8 million years ago at the beginning of the Pleistocene epoch. Three primary eruption periods in the history of the massif have been identified: ancestral, older and present. During the ancestral period between one million to two million years ago, a complex of large stratovolcanoes was created. Between 1.0 million and 0.8 million years ago, they partially collapsed, forming large (510 km wide) calderas. During the older period, which lasted from 0.8 million to 0.2 million years ago, a new complex of large stratovolcanoes developed (including Older Ruiz, Tolima, Quindio, and Santa Isabel). Once again explosive summit calderas formed from 0.2 million to 0.15 million years ago.The present period began about 150,000 years ago and involved the development of the present volcanic edifice through the emplacement of lava domes made of andesite and dacite (igneous rocks) inside older calderas. During the past 11,000 years, Nevado del Ruiz passed through at least 12 eruption stages, which included multiple slope failures (rock avalanches), pyroclastic flows and lahars leading to partial destruction of the summit domes. During the past several thousand years, eruptions of the volcanoes in the RuizTolima massif have mostly been small, and the pyroclastic flow deposits have been much less voluminous than during the Pleistocene. Since the volcano's earlier eruptions are not recorded, volcanologists have used tephrochronology to date them.During recorded history, eruptions have consisted primarily of a central vent eruption (in the caldera) followed by an explosive eruption, then lahars. Ruiz's earliest identified Holocene eruption was about 6660 BC, and further eruptions occurred in 1245 BC 150 years (dated through radiocarbon dating), about 850 BC, 200 BC 100 years, 350 AD 300 years, 675 AD 50 years, in 1350, 1541 (perhaps), 1570, 1595, 1623, 1805, 1826, 1828 (perhaps),[b] 1829, 1831, 1833 (perhaps),[b] 1845, 1916, December 1984 March 1985, September 1985 July 1991, and possibly in April 1994.[b] Many of these eruptions involved a central vent eruption, a flank vent eruption, and a phreatic (steam) explosion. Ruiz is the second-most active volcano in Colombia after Galeras.
[EX A]: What partially collapsed, forming large (510 km wide) calderas?

[EX Q]: Passage: The film stars Don McKellar as Pokey Jones, an orphaned barber in a small town near Thunder Bay, who dreams of becoming a jazz musician. One morning, Jones discovers a frozen corpse in his backyard, and soon meets Jackie Bangs, a tough and mysterious roadie who claims the dead man is her brother.
Jackie's real intention is to use the body, a vagrant unknown to anyone in town, to smuggle stolen drugs into the United States. She convinces Pokey to use his parents' car, which has not been driven in decades, to drive her to New Orleans to bury her brother. So Jackie and Pokey set out along Highway 61, coffin strapped to the top of the car, and follow Bob Dylan's famous U.S. Highway 61 south through the heart of the United States. They are pursued by Mr. Skin, who believes he is Satan and wants to claim the body because the dead man sold Mr. Skin his soul.
Peter Breck is fourth-billed as Mr. Watson, the "stage-mom" father of three girls: Mississippi, Minnesota, and Louisiana. The film also includes cameo appearances by Tav Falco, Jello Biafra, and Art Bergmann.
The film's soundtrack album includes songs by Bourbon Tabernacle Choir, Rita Chiarelli, Nash the Slash, Acid Test, Jellyfishbabies, and Tom Jones. Nash the Slash also composed the film's instrumental score.
In 2001, Playback named Highway 61 the 15th best Canadian film since 1986. McDonald won "Best Director" honours at both San Sebastian International Film Festival and Brussels International Festival of Fantasy Film, two of the top festivals in the world.
[EX A]:
What job did Jackie do before meeting Pokey?
