Passage: In 1952 the LPO negotiated a five-year contract with Decca Records, which was unusually rewarding for the orchestra, giving it a 10 per cent commission on most sales. On top of this, Boult always contributed his share of the recording fees to the orchestra's funds. In the same year, the LPO survived a crisis when Russell was dismissed as its managing director. He was an avowed member of the Communist party; when the cold war began some influential members of the LPO felt that Russell's private political affiliations compromised the orchestra, and pressed for his dismissal. Boult, as the orchestra's chief conductor, stood up for Russell, but when matters came to a head Boult ceased to protect him. Deprived of that crucial support, Russell was forced out. Kennedy speculates that Boult's change of mind was due to a growing conviction that the orchestra would be "seriously jeopardized financially" if Russell remained in post.  A later writer, Richard Witts, suggests that Boult sacrificed Russell because he believed doing so would enhance the LPO's chance of being appointed resident orchestra at the Royal Festival Hall.In 1953 Boult once again took charge of the orchestral music at a coronation, conducting an ensemble drawn from UK orchestras at the coronation of Elizabeth II. During the proceedings, he conducted the first performances of Bliss's Processional and Walton's march Orb and Sceptre.  In the same year he returned to the Proms after a three-year absence, conducting the LPO. The notices were mixed: The Times found a Brahms symphony "rather colourless, imprecise and uninspiring", but praised Boult and the orchestra's performance of The Planets. In the same year the orchestra celebrated its 21st birthday, giving a series of concerts at the Festival Hall and the Royal Albert Hall in which Boult was joined by guest conductors including Paul Kletzki, Jean Martinon,  Hans Schmidt-Isserstedt, Georg Solti, Walter Susskind and Vaughan Williams.In 1956 Boult and the LPO visited Russia. Boult had not wished to go on the tour because flying hurt his ears, and long land journeys hurt his back. The Soviet authorities threatened to cancel the tour if he did not lead it, and he felt obliged to go. The LPO gave nine concerts in Moscow and four in Leningrad.  Boult's assistant conductors were Anatole Fistoulari and George Hurst. Boult's four Moscow programmes included Vaughan Williams's Fourth and Fifth Symphonies, Holst's The Planets, Walton's Violin Concerto (with Alfredo Campoli as soloist), and Schubert's Great C major Symphony. While in Moscow, Boult and his wife visited the Bolshoi Opera and were guests at the composer Dmitri Shostakovich's 50th birthday party.After the Russian tour, Boult told the LPO that he wished to step down from the principal conductorship. He continued to be the orchestra's main conductor until his successor William Steinberg took up the post in 1959.  After the sudden resignation of Andrzej Panufnik from the City of Birmingham Symphony Orchestra (CBSO), Boult returned as principal conductor of the CBSO for the 1959–60 season. That was his last chief conductorship, though he remained closely associated with the LPO as its president and a guest conductor until his retirement. 
Question: What is the name of the person that flying hurt his ears, and long land journeys hurt his back?

Ex Output:
Boult.

Passage: William "Bill" Boss, a psychopathic prison warden, watches the end of The Human Centipede 2 (Full Sequence) with his accountant, Dwight Butler. Bill says that he hates the films as his feet are massaged by his secretary, Daisy. Daisy replies that she enjoyed them. In response, Bill sucks his finger and inserts it into Daisy's vagina, telling her that women should not be allowed to voice their opinions. Dwight interrupts, attempting to pitch a "brilliant idea" to fix the prison's horrible retention and violence rates, but he is interrupted by a phone call.
Bill and Dwight are then summoned to the scene of an assault within the prison. One of the officers has been stabbed by an inmate. As punishment, Bill decides to stomp on the arm of the prisoner, exposing the bone and causing immense pain. He promises to do it again when his bones are healed.
Back in the Warden's office, Bill receives a mysterious package. After Dwight asks what it contains, Bill reveals that it is a jar of specially imported, dried African clitorises which he eats "for strength." After eating a few, he receives a threatening prank phone call from one of the inmates. Bill waterboards him with three buckets of boiling water, horribly disfiguring him. The inmate tells Bill that he has lost his soul.
Governor Hughes arrives immediately afterwards, ordering Bill and Dwight to put a stop to the violence and promising that they will both be fired otherwise. In anger and retaliation, Bill orders a 'mass castration' of the inmates, and castrates one of the prisoners himself. He covers his face in the blood of the inmate and later eats the cooked testicles for lunch, calling it "Energy Food." Daisy is forced to perform fellatio on Bill while Dwight is in the room. Upon completing the act, Daisy eats one of the dried clitorises, mistaking them for candy. 
Question: What is the last name of the person who is interrupted by a phone call?

Ex Output:
Butler.

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: Where was Professor Kristan's mother bitten by a vampire bat?

Ex Output:

Africa.
