Example Input: Passage: Both Surfer Rosa and Steve Albini's production of the album have been influential on alternative rock, and on grunge in particular. Nirvana's Kurt Cobain cited Surfer Rosa as the basis for Nevermind's songwriting. When he first heard the album, Cobain discovered a template for the mix of heavy noise and pop he was aiming to achieve. He remarked in 1992 that he "heard songs off of Surfer Rosa that I'd written but threw out because I was too afraid to play them for anybody." Cobain hired Albini to produce Nirvana's 1993 album In Utero, primarily due to his contribution to Surfer Rosa. The Smashing Pumpkins' Billy Corgan described Surfer Rosa as "the one that made me go, 'holy shit'. It was so fresh. It rocked without being lame." Corgan was impressed by the album's drum sound, and acknowledged that The Smashing Pumpkins used to study the record for its technical elements. Musician PJ Harvey said that Surfer Rosa "blew my mind," and that she "immediately went to track down Steve Albini." Cobain listed Surfer Rosa as number 2 of the top 50 albums he thought were most influential to Nirvana's sound in his journal in 1993.People connected with the band were impressed by the record. Ivo Watts-Russell recalled: "I remember when I first heard Surfer Rosa thinking, 'I didn't know the Pixies could sound like The Fall.' That was my immediate reaction, in other words, incredibly raw." Gary Smith, who at the time was in a disagreement with the band, admitted he "was really happy that they had made such a forceful, aggressive, record." Dinosaur Jr.'s J Mascis, comparing the record to the later Pixies albums Bossanova and Trompe le Monde, said he thought that Steve Albini's production "sounded way better than the other ones."In 1991, as Pixies were recording Trompe le Monde, Albini described his impressions of Pixies during the recording of Surfer Rosa to the fan magazine Forced Exposure: "A patchwork pinch loaf from a band who at their top dollar best are blandly entertaining college rock. Their willingness to be 'guided' by their manager, their record company and their producers is unparalleled. Never have I seen four cows more anxious to be led around by their nose rings." Albini later apologized for his remarks, saying, "to this day I regret having done it. I don't think that I regarded the band as significantly as I should have.". 
Question: What is the first name of the person who was hired for their work with Surfer Rosa?
Example Output: Steve.

Example Input: Passage: Zappa's relationship with long-time manager Herb Cohen ended in 1976. Zappa sued Cohen for skimming more than he was allocated from DiscReet Records, as well as for signing acts of which Zappa did not approve. Cohen filed a lawsuit against Zappa in return, which froze the money Zappa and Cohen had gained from an out-of-court settlement with MGM over the rights of the early Mothers of Invention recordings. It also prevented Zappa having access to any of his previously recorded material during the trials. Zappa therefore took his personal master copies of the rock-oriented Zoot Allures (1976) directly to Warner Bros., thereby bypassing DiscReet.In the mid-1970s Zappa prepared material for Läther (pronounced "leather"), a four-LP project. Läther encapsulated all the aspects of Zappa's musical styles—rock tunes, orchestral works, complex instrumentals, and Zappa's own trademark distortion-drenched guitar solos. Wary of a quadruple-LP, Warner Bros. Records refused to release it. Zappa managed to get an agreement with Phonogram Inc., and test pressings were made targeted at a Halloween 1977 release, but Warner Bros. prevented the release by claiming rights over the material. Zappa responded by appearing on the Pasadena, California radio station KROQ, allowing them to broadcast Läther and encouraging listeners to make their own tape recordings. A lawsuit between Zappa and Warner Bros. followed, during which no Zappa material was released for more than a year. Eventually, Warner Bros. issued different versions of much of the Läther material in 1978 and 1979 as four individual albums (five full-length LPs) with limited promotion.Although Zappa eventually gained the rights to all his material created under the MGM and Warner Bros. contracts, the various lawsuits meant that for a period Zappa's only income came from touring, which he therefore did extensively in 1975–77 with relatively small, mainly rock-oriented, bands. Drummer Terry Bozzio became a regular band member, Napoleon Murphy Brock stayed on for a while, and original Mothers of Invention bassist Roy Estrada joined. Among other musicians were bassist Patrick O'Hearn, singer-guitarist Ray White and keyboardist/violinist Eddie Jobson. In December 1976, Zappa appeared as a featured musical guest on the NBC television show Saturday Night Live. Zappa's song "I'm the Slime" was performed with a voice-over by SNL booth announcer Don Pardo, who also introduced "Peaches En Regalia" on the same airing. In 1978, Zappa served both as host and musical act on the show, and as an actor in various sketches. The performances included an impromptu musical collaboration with cast member John Belushi during the instrumental piece "The Purple Lagoon". Belushi appeared as his Samurai Futaba character playing the tenor sax with Zappa conducting. 
Question: What is the first name of the person who prevented Zappa having access to any of his previously recorded material during the trials?
Example Output: Herb.

Example Input: Passage: College student Sarah Foster is found by the police, as she is sleepwalking in her nightgown on the road. Since the suicide of her husband Jonathon, who worked as a novelist, she is suffering from sleep disorder. A few days later, she talks to Dr Cooper, whose student she was, about the sleepwalking and a recurring nightmare, in which she is attacked by an unknown man. Cooper sends her to a therapy in a sleep laboratory. During a walk on a cemetery, Sarah talks about it with her room mate Dawn, who shows a personal interest in her professor Owen. Then an attractive man gets out of a black car and Sarah imagines him being a single. At the evening in the sleep laboratory, Dr. Koslov explains to her that her neuronal activity will be observed during the night. He also introduces her to Dr. Scott White, the director of the lab. It is the man whom Sarah has seen at the cemetery. He tells her, that a student was buried and he was there with a colleague. Sarah confides to him that she loved her husband, but not his work as a novelist.
The next morning she wakes up in a different room after a silent, dreamless night. White takes her case. He reports about irregularities in the theta waves and asks her to spend some more nights in the lab. Sarah recognizes that something is wrong.
In the lecture hall she questions the statement of her teacher, who thinks that love stories are just a dopamine kick or a bipolar disorder. But she is even more irritated when he addresses her as Miss Wells and a student repeats this name. Also Dawn, her driver's license, her diary and a dedication in her husband's book affirm this surname. Sarah is rejected by Cooper's assistant. In the sleep laboratory Dr Koslov shows her a protocol about her dream in which she is pursued. She denies having dreamed anything, but sees her signature on the form. 
Question: What is the first name of the person Dr. Cooper sends to a sleep laboratory?
Example Output:
Sarah.
