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.

Passage: Ravel was not by inclination a teacher, but he gave lessons to a few young musicians he felt could benefit from them. Manuel Rosenthal was one, and records that Ravel was a very demanding teacher when he thought his pupil had talent. Like his own teacher, Fauré, he was concerned that his pupils should find their own individual voices and not be excessively influenced by established masters. He warned Rosenthal that it was impossible to learn from studying Debussy's music: "Only Debussy could have written it and made it sound like only Debussy can sound." When George Gershwin asked him for lessons in the 1920s, Ravel, after serious consideration, refused, on the grounds that they "would probably cause him to write bad Ravel and lose his great gift of melody and spontaneity". The best known composer who studied with Ravel was probably Ralph Vaughan Williams, who was his pupil for three months in 1907–08. Vaughan Williams recalled that Ravel helped him escape from "the heavy contrapuntal Teutonic manner ... Complexe mais pas compliqué was his motto."Vaughan Williams's recollections throw some light on Ravel's private life, about which the latter's reserved and secretive personality has led to much speculation. Vaughan Williams, Rosenthal and Marguerite Long have all recorded that Ravel frequented brothels. Long attributed this to his self-consciousness about his diminutive stature, and consequent lack of confidence with women. By other accounts, none of them first-hand, Ravel was in love with Misia Edwards, or wanted to marry the violinist Hélène Jourdan-Morhange. Rosenthal records and discounts contemporary speculation that Ravel, a lifelong bachelor, may have been homosexual. Such speculation recurred in a 2000 life of Ravel by Benjamin Ivry; subsequent studies have concluded that Ravel's sexuality and personal life remain a mystery.Ravel's first concert outside France was in 1909. As the guest of the Vaughan Williamses, he visited London, where he played for the Société des Concerts Français, gaining favourable reviews and enhancing his growing international reputation.
What was the name of the person that Fauré taught?

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.
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?

Passage: William Etty was born in 1787 in York, the son of a miller and baker. He showed artistic promise from an early age, but his family were financially insecure, and at the age of 12 he left school to become an apprentice printer in Hull. On completing his seven-year indenture he moved to London "with a few pieces of chalk-crayons in colours", with the aim of emulating the Old Masters and becoming a history painter. Etty gained acceptance to the Royal Academy Schools in early 1807. After a year spent studying under renowned portrait painter Thomas Lawrence, Etty returned to the Royal Academy, drawing at the life class and copying other paintings. In 1821 the Royal Academy exhibited one of Etty's works, The Arrival of Cleopatra in Cilicia (also known as The Triumph of Cleopatra). The painting was extremely well received, and many of Etty's fellow artists greatly admired him. He was elected a full Royal Academician in 1828, ahead of John Constable. He became well respected for his ability to capture flesh tones accurately in painting and for his fascination with contrasts in skin tones.
Following the exhibition of Cleopatra, Etty attempted to reproduce its success, concentrating on painting further history paintings containing nude figures. He exhibited 15 paintings at the Summer Exhibition in the 1820s (including Cleopatra), and all but one contained at least one nude figure. In so doing Etty became the first English artist to treat nude studies as a serious art form in their own right, capable of being aesthetically attractive and of delivering moral messages. Although some nudes by foreign artists were held in private English collections, Britain had no tradition of nude painting, and the display and distribution of nude material to the public had been suppressed since the 1787 Proclamation for the Discouragement of Vice. The supposed prurient reaction of the lower classes to his nude paintings caused concern throughout the 19th century. Many critics condemned his repeated depictions of female nudity as indecent, although his portraits of male nudes were generally well received. (Etty's male nude portraits were primarily of mythological heroes and classical combat, genres in which the depiction of male nudity was considered acceptable in England.) From 1832 onwards, needled by repeated attacks from the press, Etty remained a prominent painter of nudes but made conscious efforts to try to reflect moral lessons in his work.
What is the last name of the person whose family was financially insecure?
