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 Input:
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 Output:
What were the name of three paintings civic leaders commissioned from major artists?

Passage: Fodor's Chicago 2010 ranks the hotel as having one of the best spas and one of the best pools in the city. It also ranked the hotel as a Fodor's Choice among Chicago lodging options.

Ten years after the September 11 attacks, Kamin described the building as the one that "best reveals how the Sept. 11 terrorist attacks either did or did not change architecture". Kamin clarified his belief:
Simply by virtue of standing thereand by being the tallest American building built since the 1974 completion of Sears (now Willis) TowerTrump confounds those who predicted after 9/11 that iconic skyscrapers would never be built again. At the same time, Trump's heightoriginally pegged at more than 2,000 feet but eventually scaled back to 1,362 feetsuggests that the fear spawned by the attacks did have some effect.

Passage: In 1924, Monteux began a ten-year association with the Concertgebouw Orchestra of Amsterdam, serving as "first conductor" ("eerste dirigent") alongside Willem Mengelberg, its long-serving chief conductor. The two musicians liked and respected one another, despite the difference in their approach to music-making: Monteux was scrupulous in his adherence to a composer's score and straightforward in his performances, while Mengelberg was well known for his virtuoso, sometimes wilful, interpretations and his cavalier attitude to the score ("Ve vill make some changements", as an English player quoted him). Their preferred repertoire overlapped in some of the classics, but Mengelberg had his own favourites from Bach's St. Matthew Passion to Mahler symphonies, and was happy to leave Debussy and Stravinsky to Monteux. Where their choices coincided, as in Beethoven, Brahms and Richard Strauss, Mengelberg was generous in giving Monteux at least his fair share of them.While in Amsterdam Monteux conducted a number of operas, including Pelleas et Melisande (its Dutch premiere), Carmen, Les Contes d'Hoffmann, a Lully and Ravel double bill of Acis et Galatee and L'Heure espagnole, Gluck's Iphigenie en Tauride (also brought to the Paris Opera) and Verdi's Falstaff. Toscanini had been invited to conduct the last of these, but he told the promoters that Monteux was his dearest colleague and the best conductor for Falstaff.During the first eight years of his association with the Concertgebouw, Monteux conducted between fifty and sixty concerts each season. In his final two years with the orchestra other conductors, notably the rising young Dutchman Eduard van Beinum, were allocated concerts that would previously have been given to Monteux, who amicably withdrew from his position in Amsterdam in 1934. He returned many times as a guest conductor.

Ex Output:
What is the full name of the rising conductor that was given concerts usually given to the man who conducted between fifty and sixty concerts each season?
