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.

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

Example Input: Passage: In 1987, Trent Reznor played keyboard in a Cleveland, Ohio band called the Exotic Birds, then managed by John Malm Jr. Reznor and Malm became friends, and when Reznor left the Exotic Birds to work on music of his own, Malm informally became his manager. At the time, Reznor was employed as an assistant engineer and janitor at Right Track Studios,  in Cleveland; he asked studio owner Bart Koster for permission to record some demos of his own material for free during unused studio time. Koster agreed and allowed Reznor to use it whenever it was empty, commenting that it cost him "just a little wear on [his] tape heads". While completing the early recordings, Reznor was unable to find a band that could articulate the material as he desired. Instead, inspired by Prince, Reznor played all the instruments, except drums, himself. This role remains Reznor's on most of the band's studio recordings, though he has occasionally involved other musicians and assistants. Nine Inch Nails' debut was at the Phantasy Theater in Lakewood, Ohio on October 21, 1988 as part of the Pretty Hate Machine Tour Series. In 1988, after playing its first shows supporting Skinny Puppy, Reznor's ambition for Nine Inch Nails was to release one 12-inch single on a small European label. Several labels responded favorably to the demo material and Reznor signed with TVT Records. Nine selections from the Right Track demos recorded live in November 1988, collectively known as Purest Feeling, were later released in revised form on the band's first full-length studio release, Pretty Hate Machine (1989). The overall sound on Purest Feeling is lighter than that of Pretty Hate Machine; several songs contain more live drumming and guitar work throughout, as well as a heavier use of samples from films.Reznor coined the name "Nine Inch Nails" because it "abbreviated easily", rather than for "any literal meaning". Other rumored explanations have circulated, alleging that Reznor chose to reference Jesus' crucifixion with nine-inch spikes, or Freddy Krueger's nine-inch fingernails. The English letters NIN are also noted for their resemblance to the modern Hebrew characters of the Tetragrammaton.  The Nine Inch Nails' logo, which consists of the letters [NIИ] set inside a border, was designed by Reznor and Gary Talpas, and first appeared on the music video for Nine Inch Nails' debut single, "Down in It", and was inspired by Tibor Kalman's typography on the Talking Heads album Remain in Light. Talpas, a native of Cleveland, would continue to design Nine Inch Nails packaging art until 1997.
Example Output: What is the first name of the person who was friends with John?

Example Input: Passage: On 20 July 1976, childhood friends Bernard Sumner and Peter Hook separately attended a Sex Pistols show at the Manchester Lesser Free Trade Hall. Both were inspired by the Pistols' performance. Sumner said that he felt the Pistols "destroyed the myth of being a pop star, of a musician being some kind of god that you had to worship". The following day Hook borrowed £35 from his mother to buy a bass guitar. They formed a band with Terry Mason, who had also attended the gig; Sumner bought a guitar, and Mason a drum kit. After their schoolfriend Martin Gresty declined an invitation to join as vocalist after getting a job at a factory, the band placed an advertisement for a vocalist in the Manchester Virgin Records shop. Ian Curtis, who knew them from earlier gigs, responded and was hired without audition. Sumner said that he "knew he was all right to get on with and that's what we based the whole group on. If we liked someone, they were in."Buzzcocks manager Richard Boon and frontman Pete Shelley have both been credited with suggesting the band name "Stiff Kittens", but the band settled on "Warsaw" shortly before their first gig, a reference to David Bowie's song "Warszawa". Warsaw debuted on 29 May 1977 at the Electric Circus, supporting the Buzzcocks, Penetration and John Cooper Clarke. Tony Tabac played drums that night after joining the band two days earlier. Reviews in the NME by Paul Morley and in Sounds by Ian Wood brought them immediate national exposure. Mason became the band's manager and Tabac was replaced on drums in June 1977 by Steve Brotherdale, who also played in the punk band Panik. Brotherdale tried to get Curtis to leave the band and join Panik, and even had Curtis audition. In July 1977, Warsaw recorded five demo tracks at Pennine Sound Studios, Oldham. Uneasy with Brotherdale's aggressive personality, the band fired him soon after the sessions: driving home from the studio, they pulled over and asked Brotherdale to check on a flat tyre; when he got out of the car, they drove off.In August 1977, Warsaw placed an advertisement in a music shop window seeking a replacement drummer. Stephen Morris, who had attended the same school as Curtis, was the sole respondent. Deborah Curtis, Ian's wife, stated that Morris "fitted perfectly" with the band, and that with his addition Warsaw became a "complete 'family'". To avoid confusion with the London punk band Warsaw Pakt, the band renamed themselves Joy Division in early 1978, borrowing the name from the sexual slavery wing of a Nazi concentration camp mentioned in the 1955 novel House of Dolls. In December, the group recorded their debut EP, An Ideal for Living, at Pennine Sound Studio and played their final gig as Warsaw on New Year's Eve at the Swinging Apple in Liverpool. Billed as Warsaw to ensure an audience, the band played their first gig as Joy Division on 25 January 1978 at Pip's Disco in Manchester.
Example Output:
What are the full names of the drummers of Warsaw?
