question:
Passage: 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 proletarian youth theatre. Although he did little work in this post, it shielded him from ideological attack. Much of this period was spent writing his opera, Lady Macbeth of the Mtsensk District, which was first performed in 1934. It was immediately successful, on both popular and official levels. It was described as "the result of the general success of Socialist construction, of the correct policy of the Party", and as an opera that "could have been written only by a Soviet composer brought up in the best tradition of Soviet culture".Shostakovich married his first wife, Nina Varzar, in 1932. Initial difficulties led to a divorce in 1935, but the couple soon remarried when Nina became pregnant with their first child, Galina. 
Question: What is the name of the composer whose First Symphony was conducted by Bruno Walter at its Berlin premiere?
answer:
Shostakovich.


question:
Passage: At first, Baylis presented both drama and opera at each of her theatres.  The companies were known as the "Vic-Wells".  However, for both aesthetic and financial reasons, by 1934, the Old Vic had become the home of the spoken drama, while Sadler's Wells housed both the opera and a ballet company, the latter co-founded by Baylis and Ninette de Valois in 1930.Lawrance Collingwood joined the company as resident conductor alongside Corri.  With the increased number of productions, guest conductors were recruited, including Geoffrey Toye and Anthony Collins. The increasing success of the new ballet company helped to subsidise the high cost of opera productions, enabling a further increase in the size of the orchestra, to 48 players. Among the singers in the opera company were Joan Cross and Edith Coates. In the 1930s, the company presented standard repertoire operas by Mozart, Verdi, Wagner and Puccini, lighter works by Balfe, Donizetti, Offenbach and Johann Strauss, some novelties, among which were operas by Holst, Ethel Smyth and Charles Villiers Stanford, and an unusual attempt at staging an oratorio, Mendelssohn's Elijah.In November 1937, Baylis died of a heart attack. Her three companies continued under the direction of her appointed successors: Tyrone Guthrie at the Old Vic, in overall charge of both theatres, with de Valois running the ballet, and Carey and two colleagues running the opera. In the Second World War, the government requisitioned Sadler's Wells as a refuge for those made homeless by air-raids. Guthrie decided to keep the opera going as a small touring ensemble of 20 performers. Between 1942 and the war's end in 1945, the company toured continuously, visiting 87 venues. Joan Cross led and managed the company, and also sang leading soprano roles in its productions when needed. The size of the company was increased to 50, and then to 80. By 1945, its members included singers from a new generation such as Peter Pears and Owen Brannigan, and the conductor Reginald Goodall. 
Question: What is the first name of the person who decided to keep the opera going as a small touring ensemble of 20 performer?
answer:
Tyrone.


question:
Passage: The film opens with a trio of explorers in Africa who are hiding in a cave. One of the explorers, a pregnant woman, is bitten by a vampire bat.
The film then cuts forward in time to a small European village where a series of mysterious murders are taking place. The villagers readily assemble in mob form, with torches, at the house of Professor Kristan after every murder. The villagers suspect that a giant bat is to blame for the murders. Kristan gives the villagers advice on staying safe, and assures them a scientific explanation exists.
However, in subsequent scenes, Kristan himself is revealed to be the murderer. He is seized by attacks (triggered by darkness) which transform him into a trance-like state of murderousness. After he commits a murder, he awakens from the trance with no memory of the deed, believing himself merely to have fainted.  Kristan's obliviousness is further enabled by the intervention of his loyal hunchback Zan, the only person aware of Kristan's condition. Zan follows Kristan when he is in his trances, ensuring the professor is not discovered.
An old friend of Kristan's, Dr. Bizet, arrives to visit, and soon suspects what is happening. Bizet discloses to Kristan that his mother was bitten by a vampire bat, and that traits of vampirism have likely been passed down to him per Lamarckism. (The audience now understands the pregnant explorer in the opening flashback to have been Kristan's mother.)
After Kristan's fiance is attacked by an entranced Kristan, the mob of villagers assumes Zan is culpable and chases him to the edge of a cliff inside a cave. Kristan arrives and confesses to the murders, despite Zan's protestations (aimed at saving the professor) that he, the hunchback, is in fact the murderer.  As the mob watches, Kristan throws himself over the edge of the cliff and Zan follows. 
Question: What is the first name of the person whose pregnant mother was bitten by a vampire bat?
answer:

Kristan.
