Question: Passage: Boult was born in Chester, Cheshire, in North West England, the second child and only son of Cedric Randal Boult (18531950), and his wife Katharine Florence nee 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?

Answer: Boult.

Question: Passage: During the late 12th century, about 100 years after the Norman conquest (1066), the Normans have removed the native ruling class, replacing it with a new monarchy, aristocracy and clerical hierarchy.
Thomas Becket is a Saxon protege and facilitator to the carousing King Henry II, who transforms into a man who continually invokes the "honour of God". Henry appoints Becket Lord Chancellor to have a close confidant in this position whom he can completely control. Instead, Becket becomes a major thorn in his side in a jurisdictional dispute. Henry finds his duties as king and his stale arranged marriage to be oppressive, and is described as the "perennial adolescent" by the Bishop of London. Henry is more interested in escaping his duties through drunken forays onto the hunting grounds and local brothels. He is increasingly dependent on Becket, a Saxon commoner, who arranges these debaucheries when he is not busy running Henry's court. This foments great resentment on the part of Henry's Norman noblemen, who distrust and envy this Saxon upstart, as well as the queen and Henry's mother, who see Becket as an unnatural and unseemly influence upon the royal personage.
Henry finds himself in continuous conflict with the elderly Archbishop of Canterbury, who opposes the taxation of Church property to support Henry's military campaigns in France ("Bishop, I must hire the Swiss Guards to fight for me and no one has ever paid them off with principles!"). During one of his campaigns in coastal France, he receives word that the old archbishop has "gone to God's bosom". In a burst of inspiration, Henry exercises his prerogative to pick the next Archbishop and informs an astonished Becket that he is the royal choice.
Question: What is the full name of the person who Thomas is a thorn in the side of?

Answer: King Henry II.

Question: Passage: The album was recorded in Los Angeles, California with Reign in Blood producer Rick Rubin. PopMatters reviewer Adrien Begrand observed that Rubin's production "shoves [Dave] Lombardo's drumming right up front in the mix". Guitarist Jeff Hanneman has since said that South of Heaven was the only album the band members discussed before writing the music. Aware that they "couldn't top Reign in Blood", and that whatever they recorded would be "compared to that album", he believed they "had to slow down", something Slayer had never done on albums before, or since. Guitarist Kerry King cited the need to "keep people guessing" as another reason for the musical shift. "In order to contrast the aggressive assault put forth on Reign in Blood, Slayer consciously slowed down the tempo of the album as a whole", according to Slayer's official biography. "They also added elements like undistorted guitars and toned-down vocal styles not heard on previous albums."King has since been critical of his performance, which he describes as his "most lackluster". King attributes this to the fact he had recently married, and moved to Phoenix, Arizona. Describing himself as "probably the odd man out at that point", he stated he "didn't participate as much because of that". Hanneman said: "We go through dry spells sometimes, but the good thing about having two guitar players that can write music is that you are never gonna go without. I guess at that time, Kerry was hitting a dry spell." King has also been critical of the album in general, describing it as one of his least favorite Slayer albums. He feels vocalist Tom Araya moved too far away from his regular vocal style, and "added too much singing". Drummer Dave Lombardo has since observed: "There was fire on all the records, but it started dimming when South of Heaven came into the picture. And that's me personally. Again, I was probably wanting something else."Judas Priest's "Dissident Aggressor" is the first cover version to appear on a Slayer studio album. The song was chosen due to its war-themed lyrics. Hanneman described the track as "more just like one of those odd songs that a lot of people didn't know, but it was a favorite of Kerry and I, so we just picked that one". Meanwhile, "Cleanse the Soul" has been heavily criticized by King who said that he hates the track: "That's one of the black marks in our history, in my book. I just fucking think it's horrible. [Laughs] I hate the opening riff. It's what we call a 'happy riff.' It's just like 'la-lala-la-la-la.' I can't see myself playing it, but after that, where it gets heavier, I like that section. If we ever did a medley, I'd put part of that in there." The Slayer boxset Soundtrack to the Apocalypse featured, along with four songs of the album, an early version of the title track, recorded at Hanneman's home.
Question: What song was one of Kerry King's?

Answer:
Dissident Aggressor.
