Input: Consider Input: Passage: Sometime after 4 p.m. on December 6, 1989, Marc Lepine arrived at the building housing the Ecole Polytechnique, an engineering school affiliated with the Universite de Montreal, armed with a semi-automatic rifle and a hunting knife. Lepine purchased a rifle on November 21, 1989, in a Checkmate Sports store in Montreal. He had told the clerk that he was going to use it to hunt small game. Lepine had been in and around the Ecole Polytechnique building at least seven times in the weeks leading up to December 6.
Lepine first sat in the office of the registrar on the second floor for a while. While there, he was seen rummaging through a plastic bag. He did not speak to anyone, even when a staff member asked if she could help him. Lepine left the office and was subsequently seen in other parts of the building before entering a second-floor mechanical engineering class of about sixty students at about 5:10 p.m. After approaching the student giving a presentation, he asked everyone to stop everything and ordered the women and men to opposite sides of the classroom. No one moved at first, believing it to be a joke until he fired a shot into the ceiling.Lepine then separated the nine women from the approximately fifty men and ordered the men to leave. He asked the remaining women whether they knew why they were there, and when one student replied "no," he answered: "I am fighting feminism." One of the students, Nathalie Provost, said, "Look, we are just women studying engineering, not necessarily feminists ready to march on the streets to shout we are against men, just students intent on leading a normal life." Lepine responded, "You're women, you're going to be engineers. You're all a bunch of feminists. I hate feminists." He then opened fire on the students from left to right, killing six, and wounding three others, including Provost. Before leaving the room, he wrote the word shit twice on a student project.Lepine continued into the second-floor corridor and wounded three students before entering another room where he twice attempted to shoot a female student. When his weapon failed to fire, he entered the emergency staircase where he was seen reloading his gun. He returned to the room he had just left, but the students had locked the door; Lepine failed to unlock it with three shots fired into the door. Moving along the corridor, he shot at others, wounding one, before moving towards the financial services office where he shot and killed a woman through the window of the door she had just locked.
Question: What is the first name of the person who sat in the office of the registrar on the second floor for a while?

Output: Marc.

Input: Consider Input: Passage: Although the publicity generated by Five Leaves Left was minor, Boyd was keen to build on what momentum there was. Drake's second album, 1971's Bryter Layter, again produced by Boyd and engineered by John Wood, introduced a more upbeat, jazzier sound.Disappointed by his debut's poor commercial performance, Drake sought to move away from his pastoral sound, and agreed to Boyd's suggestions to include bass and drum tracks. "It was more of a pop sound, I suppose," Boyd later said. "I imagined it as more commercial." Like its predecessor, the album featured musicians from Fairport Convention, as well as contributions from John Cale on two songs: "Northern Sky" and "Fly". Trevor Dann noted that while sections of "Northern Sky" sound more characteristic of Cale, the song was the closest Drake came to a release with chart potential. Cale used heroin during this period, and his older friend Brian Wells suspected that Drake was also using.Boyd and Wood were confident that Bryter Layter would be a success, but it sold fewer than 3,000 copies. Reviews were again mixed: while Record Mirror praised Drake as a "beautiful guitaristclean and with perfect timing, [and] accompanied by soft, beautiful arrangements", Melody Maker described the album as "an awkward mix of folk and cocktail jazz".Soon after its release, Boyd sold Witchseason to Island Records, and moved to Los Angeles to work with Warner Brothers to develop film soundtracks. The loss of his mentor, coupled with the album's poor sales, led Drake into further depression. His attitude to London had changed: he was unhappy living alone, and visibly nervous and uncomfortable performing at a series of concerts in early 1970. In June, Drake gave one of his final live appearances at Ewell Technical College, Surrey. Ralph McTell, who also performed that night, remembered: "Nick was monosyllabic. At that particular gig he was very shy. He did the first set and something awful must have happened. He was doing his song 'Fruit Tree' and walked off halfway through it."In 1971, Drake's family persuaded him to visit a psychiatrist at St Thomas's Hospital, London. He was prescribed antidepressants, but felt uncomfortable and embarrassed about taking them, and tried to hide the fact from his friends. He worried about their side effects and was concerned about how they would react with his regular cannabis use.Island Records urged Drake to promote Bryter Layter through interviews, radio sessions and live appearances. Drake, who by this time was smoking what Kirby described as "unbelievable amounts" of cannabis and exhibiting "the first signs of psychosis", refused. Disappointed by the reaction to Bryter Layter, he turned his thoughts inwards, and withdrew from family and friends. He rarely left his flat, and then only to play an occasional concert or to buy drugs. His sister recalled: "This was a very bad time. He once said to me that everything started to go wrong from [this] time on, and I think that was when things started to go wrong.".
Question: What is the last name of the person who agreed to include bass and drum tracks?

Output: Northern Sky.
