Detailed Instructions: 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.
See one example below:
Problem: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Explanation: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

Problem: 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.
Solution:
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?
