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.

Q: Passage: Scene: A Ruined Temple on the Summit of Mount Olympus
On Mount Olympus, the elderly deities complain of feeling old and lament their waning influence on Earth.  Mercury complains that the older gods are lazy and leave all their duties to him, while he gets no credit for all his drudgery.  Jupiter says that matters have reached a crisis, but he is unsure what can be done about it.  Just then, the gods see a swarm of mortals ascending the mountain and withdraw to observe them from a distance.
Thespis's acting company enters for a picnic celebrating the marriage of two of its members, Sparkeion and Nicemis.  The actors, being cheap, have failed to contribute substantial food items to the picnic.  Sparkeion flirts with his former fiancée, Daphne, which annoys Nicemis.  In retaliation, Nicemis flirts with her old suitor, Thespis, but he declines to flirt back.  Thespis explains to his troupe that a successful manager must be aloof from those he manages, or he will lose his authority.
Jupiter, Mars and Apollo enter.  All of the actors flee in terror, except for Thespis.  Jupiter asks Thespis whether he is impressed with the father of the gods.  Thespis replies that the gods are unimpressive and suggests that they go down to earth in disguise to "mingle" and judge for themselves what people think of them.  They agree to invest the actors with their powers, as they take a merry holiday below on Earth.  Thespis agrees that he and his company will keep things running on Mount Olympus during the gods' absence.  Each actor takes the place of one of the gods, with Thespis himself replacing Jupiter.  Mercury stays behind to offer any advice the actors may need.

A: What are the names of the gods that see a swarm of mortals ascending the mountain?

Q: Passage: The first years of the 14th century were marked by famines, culminating in the Great Famine of 1315–17. The causes of the Great Famine included the slow transition from the Medieval Warm Period to the Little Ice Age, which left the population vulnerable when bad weather caused crop failures. The years 1313–14 and 1317–21 were excessively rainy throughout Europe, resulting in widespread crop failures. The climate change—which resulted in a declining average annual temperature for Europe during the 14th century—was accompanied by an economic downturn.
These troubles were followed in 1347 by the Black Death, a pandemic that spread throughout Europe during the following three years. The death toll was probably about 35 million people in Europe, about one-third of the population. Towns were especially hard-hit because of their crowded conditions. Large areas of land were left sparsely inhabited, and in some places fields were left unworked. Wages rose as landlords sought to entice the reduced number of available workers to their fields. Further problems were lower rents and lower demand for food, both of which cut into agricultural income. Urban workers also felt that they had a right to greater earnings, and popular uprisings broke out across Europe. Among the uprisings were the jacquerie in France, the Peasants' Revolt in England, and revolts in the cities of Florence in Italy and Ghent and Bruges in Flanders. The trauma of the plague led to an increased piety throughout Europe, manifested by the foundation of new charities, the self-mortification of the flagellants, and the scapegoating of Jews. Conditions were further unsettled by the return of the plague throughout the rest of the 14th century; it continued to strike Europe periodically during the rest of the Middle Ages.

A: In terms of percentage how many people died from the Black Death?

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.

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?
