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: 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.
[EX A]: What is the first name of the person who was friends with John?

[EX Q]: Passage: In 1885–87 the partnership designed Abbeystead House for the 4th Earl of Sefton in North Lancashire. Hubbard describes this as "the finest of Douglas's Elizabethan houses, and one of the largest which he ever designed". During this time additions were made to Jodrell Hall in Cheshire and Halkyn Castle in Flintshire. In 1885 the Castle Hotel at Conwy, Caernarfonshire, was remodelled, and in 1887–88 a strongroom was added to Hawarden Castle, followed by a porch in 1890. During this period more buildings were added to the Eaton Hall estate, and these included houses and cottages, such as Eccleston Hill, and Eccleston Ferry House, and farms such as Saighton Lane Farm. In 1890–91 an obelisk was built in the Belgrave Avenue approach to Eaton Hall. The last house designed by Douglas on a large scale was Brocksford Hall (1893) in Derbyshire. This was a country house in Elizabethan style using diapered brick and stone dressings with a clock tower. In Chester city centre, 38 Bridge Street (1897) is a timber-framed shop that incorporates a section of Chester Rows and contains heavily decorated carving. From 1892 the partnership designed houses and cottages in Port Sunlight for Lever Brothers. Also in the village they designed the Dell Bridge (1894), and the school (1894–96), which is now called the Lyceum. In 1896 Douglas designed a house for himself, Walmoor Hill in Dee Banks, Chester, in Elizabethan style. Between 1895 and 1897 he designed a range of buildings on the east side of St Werburgh Street in the centre of Chester. At its south end, on the corner of Eastgate Street, is a bank whose ground storey is built in stone, and behind this leading up St Werburgh Street, the ground storey consists of shop fronts. Above this the range consists of two storeys plus an attic, which are covered in highly ornamented timber-framing. On the first floor is a series of oriel windows, the second floor is jettied, and at the top are eleven gables. Pevsner considers that this range of buildings is "Douglas at his best (though also at his showiest)". Hubbard expresses the opinion that "in this work, the city's half-timber revival reached its very apogee".
[EX A]: What was the name of the street that Douglas had created his showiest buildings?

[EX Q]: Passage: Jay Pritzker Pavilion cost $60 million, a quarter of which came from the Pritzker family donation. It includes 4,000 fixed seats and a 95,000-square-foot (8,800 m2) Great Lawn that can accommodate an additional 7,000 people. The pavilion was built above and behind the Harris Theater, which has the benefit that Millennium Park's indoor and outdoor performance venues share a loading dock, rehearsal rooms and other backstage facilities.The bandshell's brushed stainless steel headdress frames the 120-foot (37 m) proscenium theatre; the main stage can accommodate a full orchestra and chorus of 150 members. The bandshell is connected to a trellis of interlocking crisscrossing steel pipes that support the innovative sound system, which mimics indoor concert hall acoustics. The pavilion has restrooms on both its east and west sides. It is one of two features in the park to include accessible restrooms; the other is McCormick Tribune Plaza & Ice Rink. The majority of the park's 123 toilet fixtures (78 for women, 45 for men) are located in underground arcades to the east and west of the pavilion, with the ones on the east being heated for winter use.Millennium Park is built on top of a large underground parking garage. Construction started before the park's design was completed, and in January 2000, 17 additional caissons had to be added to the partially built garage to support the weight of Gehry's pavilion. In April the tops of all these caissons had to be rebuilt for changes in the pavilion's foundation.U.S. Equities Realty was responsible for negotiating contracts with Gehry and all contractors. Walsh Construction and its subcontractors were hired to execute three elements of Gehry's design: the structural steel supporting the stainless steel ribbons, the ribbons themselves and the trellis and associated sound system.
