input question: Given the following context:  After graduation, Shostakovich initially embarked on a dual career as concert pianist and composer, but his dry style of playing was often unappreciated (his American biographer, Laurel Fay, comments on his "emotional restraint" and "riveting rhythmic drive"). He nevertheless won an "honorable mention" at the First International Chopin Piano Competition in Warsaw in 1927. He attributed the disappointment at the competition to suffering from appendicitis and the jury being all-Polish. He had his appendix removed in April 1927. After the competition Shostakovich met the conductor Bruno Walter, who was so impressed by the composer's First Symphony that he conducted it at its Berlin premiere later that year. Leopold Stokowski was equally impressed and gave the work its U.S. premiere the following year in Philadelphia and also made the work's first recording. Shostakovich concentrated on composition thereafter and soon limited his performances primarily to those of his own works. In 1927 he wrote his Second Symphony (subtitled To October), a patriotic piece with a great pro-Soviet choral finale. Owing to its experimental nature, as with the subsequent Third Symphony, it was not critically acclaimed with the enthusiasm given to the First. 1927 also marked the beginning of Shostakovich's relationship with Ivan Sollertinsky, who remained his closest friend until the latter's death in 1944. Sollertinsky introduced the composer to the music of Mahler, which had a strong influence on his music from the Fourth Symphony onwards. While writing the Second Symphony, Shostakovich also began work on his satirical opera The Nose, based on the story by Nikolai Gogol. In June 1929, against the composer's own wishes, the opera was given a concert performance; it was ferociously attacked by the Russian Association of Proletarian Musicians (RAPM). Its stage premiere on 18 January 1930 opened to generally poor reviews and widespread incomprehension among musicians.In the late 1920s and early 1930s, Shostakovich worked at TRAM, a...  answer the following question:  What is the name of the person whose music, from the Fourth Symphony onwards, was strongly influenced by the music of Mahler????
output answer: Shostakovich

Given the following context:  Impresario and author John Hollingshead, the lessee of London's Gaiety Theatre since 1868, had produced a number of successful musical burlesques and operettas there. Indeed, Hollingshead "boasted that he kept alight 'the sacred lamp of burlesque.'" Gilbert and Sullivan were each well acquainted with the Gaiety and its house artistes.  Gilbert's Robert the Devil (a burlesque of the opera Robert le Diable) had been on the programme on the theatre's opening night on 21 December 1868, with Nellie Farren in the title role, and played successfully for over 100 nights. Constance Loseby and Annie Tremaine (both of whom had roles in Thespis) were also in the cast of Robert, and Arthur Sullivan was in the audience on that opening night as one of Hollingshead's guests. It was a great success, "received with a storm of approbation". Less successfully, Gilbert had also written a play for the theatre in 1869 called An Old Score. Hollingshead would later say that the piece was "too true to nature". By late September or early October 1871, Gaiety programmes announced that "The Christmas Operatic Extravaganza will be written by W. S. Gilbert, with original music by Arthur Sullivan." There would be prominent roles for the popular comedian J. L. Toole, as well as Farren, the theatre's star "principal boy" in all of its burlesques. How and when the pair came to collaborate on Thespis is uncertain. Gilbert was a logical choice for the assignment. With seven operas and plays premièring that year and over a dozen other burlesques, farces and extravaganzas under his belt, he was well known to London theatregoers as a comic dramatist. Sullivan, however, was at this point mainly known for his serious music. His completed music that year included the choral cantata On Shore and Sea, a suite of incidental music for Shakespeare's The Merchant of Venice, and numerous hymns, including "Onward, Christian Soldiers". He did have two comic operas to his credit, Cox and Box (1866) and The Contrabandista (1867), but the latter was four years in...  answer the following question:  What is the full name of the burlesque that was a great success and received with a storm of approbation?
----
Answer: Robert the Devil

Problem: Given the question: Given the following context:  With the help of his Peruvian friend Ricardo, Oliver, an American hedge fund banker, buys debts owed by the Peruvian government to landowners.  Though the deals are lucrative, Ricardo has lingering doubts about whether they are helping Peruvians.  At the same time, Maria, a nurse at an underfunded hospital in Lima, cares for her elderly, ailing mother, Gloria.  Though Gloria needs hospital care, Maria can not convince her superior, Dr. Cerrón, to admit her, as Gloria's illness is not life-threatening.  In the Andes, a mountain farmer, Florentino, struggles to convince his neighbors not to sell their ancestral land to Caravedo, a developer who has promised to bring modernization and jobs to the area.  Florentino has a strained relationship with his son, Diego, who dreams of being a pilot. Oliver's boss, Nathan, tells him they need to pull out of Peru, as the company needs an immediate influx of money.  Stunned, Oliver insists Nathan give him time to close a potential deal with Caravedo that could solve their problems.  Nathan gives him one week.  Though his family is distraught that he is returning again to Peru, Oliver tells his wife he must close the deal or all of their previous sacrifices will be for nothing.  Oliver recruits Ricardo to research Caravedo.  After Oliver aggressively pressures the Peruvian finance minister to repay debts, Ricardo walks away from the Caravedo deal.  He returns shortly but demands Oliver promise to abort any potential deals with Caravedo if they turn out to be exploitative.  answer the following question:  In what location does Diego's dad work?
