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 time Hope was exhibited, Watts had already committed himself to donate his most significant works to the nation, and although he received multiple offers for the painting he thought it inappropriate not to include Hope in this donation, in light of the fact that it was already being considered one of his most important pictures. In mid-1886 Watts and his assistant Cecil Schott painted a duplicate of the piece, with the intention that this duplicate be donated to the nation allowing him to sell the original. Although the composition of this second painting is identical, it is radically different in feel. The central figure is smaller in relation to the globe, and the colours darker and less sumptuous, giving it an intentionally gloomier feel than the original.In late 1886 this second version was one of nine paintings donated to the South Kensington Museum (now the Victoria and Albert Museum) in the first instalment of Watts's gift to the nation. Meanwhile, the original was briefly displayed in Nottingham before being sold to the steam tractor entrepreneur Joseph Ruston in 1887. Its whereabouts was long unknown until in 1986 it was auctioned at Sotheby's for £869,000 (about £2,500,000 in 2019 terms), 100 years after its first exhibition.On their donation to the South Kensington Museum, the nine works donated by Watts were hung on the staircase leading to the library, but Hope proved a popular loan to other institutions as a symbol of current British art. At the Royal Jubilee Exhibition of 1887 in Manchester, an entire wall was dedicated to the works of Watts. Hope, only recently completed but already the most famous of Watts's works, was placed at the centre of this display. It was then exhibited at the 1888 Melbourne Centennial Exhibition and the 1889 Exposition Universelle in Paris, before being moved to Munich for display at the Glaspalast. In 1897 it was one of the 17 Watts works transferred to the newly created National Gallery of British Art (commonly known as the Tate Gallery, now Tate Britain); at the time, Watts was so highly regarded that an entire room of the new museum was dedicated to his works. The Tate Gallery considered Hope one of the highlights of their collection and did not continue the South Kensington Museum's practice of lending the piece to overseas exhibitions.
[EX A]: What is the last name of the person who wanted to donate a duplicate to the nation so he could sell the original?

[EX Q]: Passage: In 2007, Elderly sold more than 16,000 instruments. The company is a  dealer of Martin guitars, as well as other mainstream brands such as Guild and Fender. It sells used Gibson instruments, but not new models as a result of the Gibson lawsuit. Although the bulk of its business comes from guitar sales, the company carries a range of other instruments, such as banjos, ukuleles, mandolins, accordions, concertinas, bouzoukis, sitars, musical saws, and African thumb pianos. Some of the rarer instruments are purchased as collectibles. Elderly is an exclusive retailer of "LunchBox-A-LeLes", ukuleles made from various tin lunch box designs. The journal Bluegrass Unlimited has noted Elderly Instruments for carrying "elite" brands of instruments, such as Paul Duff mandolins, Huss & Dalton acoustic guitars, Stelling banjos, and Nash electric guitars. Elderly was once one of only two American retailers for Apitius Mandolins, now only sold directly. As part of its consignment business, Elderly sells "collections" of instruments that sometimes have rich histories. In September 2006, it placed the Dopyera family's personal collection of resonator instruments up for sale, including some of the Dobro and National brands. The Dopyera family was responsible for founding those companies and innovating the resonator instrument trade.Elderly Instruments carries a number of Martin guitars, including valuable vintage models. In interviews, Werbin frequently mentions Martins made before World War II as especially desirable and "memorable" pieces of the Elderly Instruments inventory. The guitars are sought after by musicians from the bluegrass and other genres. Werbin purchases some of the more valuable or interesting instruments for his personal collection, and has lent them to museums as temporary exhibits.Periodicals for the bluegrass genre such as Bluegrass Canada and Bluegrass Now have featured stories about Elderly and its selection of bluegrass instruments and repair services. Elderly employees maintain connections with the bluegrass industry by attending trade shows such as the International Bluegrass Association Trade Show in Louisville, Kentucky. At these shows, Elderly showcases typical bluegrass instruments, such as banjos, guitars, mandolins, fiddles and resophonic guitars, to musicians and businesspeople. Elderly Instruments staff members have set up organizations such as the "Friends of Bluegrass" to support local bluegrass musicians.Michigan Living magazine noted Elderly's liberal policy regarding the handling of instruments, something Werbin attributes to his difficulty shopping for Martin guitars in New York City in the 1960s. The magazine also notes that customers are encouraged to pick up and play any instrument, an unusual policy for a high-end instrument retailer. Impromptu "jam sessions" are frequent in the store, as customers try out guitars.
[EX A]: What is the name of the organization set up to support bluegrass musicians by the employees of the company that sold over 16,000 instruments in 2007?

[EX Q]: Passage: On the planet Krypton, Jor-El of the Kryptonian high council discovers the planet will soon be destroyed when its red supergiant sun goes supernova. Despite his insistence, he fails to convince the other council members. To save his infant son, Kal-El, Jor-El launches him in a spaceship to Earth, a planet with a suitable atmosphere where his dense molecular structure will give him superhuman strength and other powers. Shortly after the launch, Krypton's sun explodes, destroying the planet.
The ship crash-lands on Earth near Smallville, Kansas. Kal-El, who is now three years old, is found by Jonathan and Martha Kent, who are astonished when he lifts their truck. They take him back to their farm and raise him as their own, naming him Clark after Martha's maiden name.
At 18, soon after Jonathan's death from a heart attack, Clark hears a psychic "call" and discovers a glowing green crystal in the remains of his spacecraft. It compels him to travel to the Arctic where it builds the Fortress of Solitude, resembling the architecture of Krypton. Inside, a hologram of Jor-El explains Clark's true origins, and after 12 further years of educating him on his powers and his reason for being sent to Earth, he leaves the Fortress wearing a blue and red suit with a red cape and the House of El family crest emblazoned on his chest and becomes a reporter at the Daily Planet in Metropolis. He meets and develops a romantic attraction to coworker Lois Lane.
