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: On 18 February 1914 The Rite received its first concert performance (the music without the ballet), in St Petersburg under Serge Koussevitzky. On 5 April that year, Stravinsky experienced for himself the popular success of The Rite as a concert work, at the Casino de Paris. After the performance, again under Monteux, the composer was carried in triumph from the hall on the shoulders of his admirers. The Rite had its first British concert performance on 7 June 1921, at the Queen's Hall in London under Eugene Goossens. Its American premiere occurred on 3 March 1922, when  Stokowski included it in a Philadelphia Orchestra programme. Goossens was also responsible for introducing The Rite to Australia on 23 August 1946 at the Sydney Town Hall, as guest conductor of the Sydney Symphony Orchestra.Stravinsky first conducted the work in 1926, in a concert given by the Concertgebouw Orchestra in Amsterdam; two years later he brought it to the Salle Pleyel in Paris for two performances under his baton. Of these occasions he later wrote that "thanks to the experience I had gained with all kinds of orchestras ... I had reached a point where I could obtain exactly what I wanted, as I wanted it". Commentators have broadly agreed that the work has had a greater impact in the concert hall than it has on the stage; many of Stravinsky's revisions to the music were made with the concert hall rather than the theatre in mind. The work has become a staple in the repertoires of all the leading orchestras, and has been cited by Leonard Bernstein as "the most important piece of music of the 20th century".In 1963, 50 years after the premiere, Monteux (then aged 88) agreed to conduct a commemorative performance at London's Royal Albert Hall. According to Isaiah Berlin, a close friend of the composer, Stravinsky informed him that he had no intention of hearing his music being "murdered by that frightful butcher". Instead he arranged tickets for that particular evening's performance of Mozart's opera The Marriage of Figaro, at Covent Garden. Under pressure from his friends, Stravinsky was persuaded to leave the opera after the first act. He arrived at the Albert Hall just as the performance of The Rite was ending; composer and conductor shared a warm embrace in front of the unaware, wildly cheering audience. Monteux's biographer John Canarina provides a different slant on this occasion, recording that by the end of the evening Stravinsky had asserted that "Monteux, almost alone among conductors, never cheapened Rite or looked for his own glory in it, and he continued to play it all his life with the greatest fidelity". 
Question: What is the last name of the person who Stravinsky told he had no intention of hearing his music being "murdered by that frightful butcher?"?
Example Output: Berlin.

Example Input: Passage: Set during the American Civil War, the story focuses on Charlotte Lovell and her cousin Delia, whose wedding day is disrupted when her former fiance Clem Spender returns following a two-year absence. Delia proceeds to marry Jim Ralston, and Charlotte comforts Clem, who enlists in the Union Army and is later killed in battle. Shortly after his death, Charlotte discovers she is pregnant with Clem's child, and in order to escape the stigma of an illegitimate child, she journeys West to have her baby, a daughter she names Clementina (or "Tina").
Following the end of the war, Charlotte and Tina relocate to Philadelphia, where Charlotte opens an orphanage. Delia is the mother of two children, and Charlotte is engaged to marry Joe Ralston, her cousin's brother-in-law. On her wedding day, Charlotte tells Delia that Tina is her child by Clem, and Delia stops Joe from marrying Charlotte by telling him that she is in poor health. The cousins become estranged, but when Jim is killed in a horse riding accident, Delia invites Charlotte and Tina to move in with her and her children. Tina, unaware Charlotte is her birth mother, assumes the role of Delia's daughter and calls Charlotte her aunt.
Fifteen years pass, and Tina is engaged to wealthy Lanning Halsey. Still unaware Charlotte is her mother, she begins to resent what she considers her interference in her life, and when Delia offers to formally adopt Tina in order to provide her with a reputable name and a prominent position in society, she gladly accepts. Charlotte intends to tell Tina the truth before her wedding but finds herself unable to do so. 
Question: What is the full name of the cousin of the woman who's former fiance returns after a two year absence?
Example Output:
Charlotte Lovell.
