Example Input: Passage: Boult was born in Chester, Cheshire, in North West England, the second child and only son of Cedric Randal Boult (1853–1950), and his wife Katharine Florence née Barman (d. 1927). Cedric Boult was a Justice of the Peace and a successful businessman connected with Liverpool shipping and the oil trade; Cedric and his family had "a Liberal Unitarian outlook on public affairs" with a history of philanthropy. When Boult was two years old the family moved to Blundellsands, where he was given a musical upbringing. From an early age he attended concerts in Liverpool, conducted mostly by Hans Richter. He was educated at Westminster School in London, where in his free time he attended concerts conducted by, among others, Sir Henry Wood, Claude Debussy, Arthur Nikisch, Fritz Steinbach, and Richard Strauss. His biographer, Michael Kennedy, writes, "Few schoolboys can have attended as many performances by great artists as Boult heard between 1901 and October 1908, when he went up to Christ Church, Oxford." While still a schoolboy, Boult met the composer Edward Elgar through Frank Schuster, a family friend.At Christ Church college at Oxford, where he was an undergraduate from 1908 to 1912, Boult studied history but later switched to music, in which his mentor was the musical academic and conductor Hugh Allen. Among the musical friends he made at Oxford was Ralph Vaughan Williams, who became a lifelong friend. In 1909 Boult presented a paper to an Oxford musical group, the Oriana Society, entitled Some Notes on Performance, in which he laid down three precepts for an ideal performance: observance of the composer's wishes, clarity through emphasis on balance and structure, and the effect of music made without apparent effort. These guiding principles lasted throughout his career. He was president of the University Musical Club for the year 1910, but his interests were not wholly confined to music: he was a keen rower, stroking his college boat at Henley, and all his life he remained a member of the Leander Club. 
Question: What is the last name of the person whose mentor was the musical academic and conductor Hugh Allen?
Example Output: Boult.

Example Input: Passage: Sometime after 4 p.m. on December 6, 1989, Marc Lépine arrived at the building housing the École Polytechnique, an engineering school affiliated with the Université de Montréal, armed with a semi-automatic rifle and a hunting knife. Lépine 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. Lépine had been in and around the École Polytechnique building at least seven times in the weeks leading up to December 6.
Lépine 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. Lépine 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.Lépine 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." Lépine 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.Lépine 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; Lépine 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 last name of the person who did not speak to anyone when a staff member asked if they could help him?
Example Output: Lépine.

Example Input: Passage: After the band released two slow-paced albums in a row, R.E.M.'s 1994 album Monster was, as Buck said, "a 'rock' record, with the rock in quotation marks." In contrast to the sound of its predecessors, the music of Monster consisted of distorted guitar tones, minimal overdubs, and touches of 1970s glam rock. Like Out of Time, Monster topped the charts in both the US and UK. The record sold about nine million copies worldwide. The singles "What's the Frequency, Kenneth?" and "Bang and Blame" were the band's last American Top 40 hits, although all the singles from Monster reached the Top 30 on the British charts. Warner Bros. assembled the music videos from the album as well as those from Automatic for the People for release as Parallel in 1995.In January 1995, R.E.M. set out on its first tour in six years. The tour was a huge commercial success, but the period was difficult for the group. On March 1, Berry collapsed on stage during a performance in Lausanne, Switzerland, having suffered a brain aneurysm. He had surgery immediately and recovered fully within a month. Berry's aneurysm was only the beginning of a series of health problems that plagued the Monster tour. Mills had to undergo abdominal surgery to remove an intestinal adhesion in July; a month later, Stipe had to have an emergency surgery to repair a hernia. Despite all the problems, the group had recorded the bulk of a new album while on the road. The band brought along eight-track recorders to capture its shows, and used the recordings as the base elements for the album. The final three performances of the tour were filmed at the Omni Coliseum in Atlanta, Georgia and released in home video form as Road Movie.R.E.M. re-signed with Warner Bros. Records in 1996 for a reported $80 million (a figure the band constantly asserted originated with the media), rumored to be the largest recording contract in history at that point. The group's 1996 album New Adventures in Hi-Fi debuted at number two in the US and number one in the UK. The five million copies of the album sold were a reversal of the group's commercial fortunes of the previous five years. Time writer Christopher John Farley argued that the lesser sales of the album were due to the declining commercial power of alternative rock as a whole. That same year, R.E.M. parted ways with manager Jefferson Holt, allegedly due to sexual harassment charges levied against him by a member of the band's home office in Athens. The group's lawyer Bertis Downs assumed managerial duties. 
Question: What group used the eight-track recordings as the base elements for the album?
Example Output:
R.E.M.
