TASK DEFINITION: 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.
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?

PROBLEM: Passage: In 1916, childhood best friends, Bob Wilson and Fred von Bergen, are test pilots working for an American company that builds bombers for the European allies. Since he is German-born and faces prejudice against his heritage, Fred loses his job and, unable to find other employment, decides to return to Germany to fight for his homeland. Although he has no special attachment to the German cause, Bob quits the aviation company and joins his friend in Germany. 
On their way to a German airfield, Red Cross nurse Alida Hoffman accidentally runs Bob and Fred off the road, Both men are immediately drawn to Alida, especially Bob although Fred is more shy. After Bob's first unsuccessful mission, Captain Wolters, the squadron's tyrannical leader, expresses his doubt about his loyalty but, desperate for pilots, gives him another chance. 
As the United States is drawn into the war, instead of sending him into a crucial air battle, Wolters arrests Bob. Fred, heartbroken that Alida has chosen Bob, quarrels with his friend, calling him a coward. Later, however, Fred allows his friend to escape from a firing squad and flee to the Allied lines. 
To prove his allegiance, Bob leads British bombers to the German base, while Fred is told by Wolters that he must shoot down Bob to prove his loyalty. Neither man is capable of killing the other, and, in the end, Fred sacrifices his life for Bob. After the war, Bob returns to Germany to marry Alida. The newly married couple then returns to the United States, and pay their respects to Fred's mother.

SOLUTION: What is the first name of the man that is fired for being German-born?

PROBLEM: Passage: From almost the start of his career Barbirolli was a frequent recording artist. As a young cellist he made four records for Edison Bell in 1911, with piano accompaniment by his sister Rosa, and as part of the Kutcher and the Music Society string quartets he recorded music by Mozart, Purcell, Vaughan Williams and others in 1925 and 1926. As a conductor he began recording in 1927 for the National Gramophonic Society (an offshoot of The Gramophone). Among his records from that period was the first to be made of Elgar's Introduction and Allegro for Strings. On hearing it, the composer said, "I'd never realised it was such a big work." Elgar, despite an extensive discography as a conductor, never recorded the work himself, and some have speculated that "the breadth, nobility and lyrical poetry" of Barbirolli's interpretation left the composer disinclined to compete. In 1928 Barbirolli made some recordings for the Edison Bell label.  The same year, he began his long association with the His Master's Voice (HMV) label. Immediately after the LSO concert at which he had stood in for Beecham, he was approached by Fred Gaisberg, the chief recording producer for HMV who signed him for his company shortly afterwards. An HMV colleague of Gaisberg described Barbirolli as "a treasure", because he "could accompany Chaliapin without provoking an uproar, win golden opinions from Jascha Heifetz, Artur Rubinstein, Fritz Kreisler and Pablo Casals, and conduct one of the finest recorded performances of the Quintet from Meistersinger".
Many of Barbirolli's pre-war recordings for HMV were of concertos. His reputation as an accompanist tended to obscure his talents as a symphonic conductor, and later, his detractors in New York "damned him with faint praise by exalting his powers as an accompanist and then implying that that was where it all stopped." Barbirolli became very sensitive on this point, and for many years after the war he was reluctant to accompany anyone in the recording studio. Among his early HMV records are works, mainly concertos, by Brahms, Bruch, Chopin, Dvořák, Glazunov, Mendelssohn, Mozart, Schumann, Sibelius, Tchaikovsky and Vieuxtemps. From the 1990s onwards, archive recordings of Barbirolli's early concerts in New York have been issued on CD. Kennedy wrote in 2004 that they "prove that the orchestra played superbly for him and that the criticism of him was largely unjustified." Recordings from this period include symphonies by Beethoven, Mendelssohn, Mozart, Schubert, Schumann, Sibelius and Tchaikovsky, and other orchestral music by Berlioz, Debussy, Menotti, Purcell, Ravel, Respighi, and Rimsky-Korsakov.

SOLUTION:
What is the first name of the person who described Barbirolli as "a treasure", because he "could accompany Chaliapin without provoking an uproar?"?
