PROBLEM: Passage: "Imagine" is a song co-written and performed by English musician John Lennon. The best-selling single of his solo career, its lyrics encourage the listener to imagine a world at peace without the barriers of borders or the divisions of religion and nationality and to consider the possibility that the whole of humanity would live unattached to material possessions. Shortly before his death, Lennon said that much of the song's "lyric and content" came from his wife Yoko Ono, and in 2017, she received a co-writing credit.Lennon and Ono co-produced the song and album of the same name with Phil Spector. Recording began at Lennon's home studio at Tittenhurst Park, England, in May 1971, with final overdubs taking place at the Record Plant, in New York City, during July. One month after the September release of the LP, Lennon released "Imagine" as a single in the United States; the song peaked at number three on the Billboard Hot 100 and the LP reached number one on the UK chart in November, later becoming the most commercially successful and critically acclaimed album of Lennon's solo career. Although not originally released as a single in the United Kingdom, it was released in 1975 to promote Shaved Fish, a compilation LP and it reached number six on the chart that year. The photograph on the cover was taken by May Pang in 1974. The song has since sold more than 1.6 million copies in the UK; it reached number one following Lennon's murder in December 1980. In 1985, the Central Park Conservancy memorialised a portion of the park in honour of Lennon, called Strawberry Fields, with a mosaic that reads "Imagine".BMI named "Imagine" one of the 100 most-performed songs of the 20th century. The song ranked number 30 on the Recording Industry Association of America's list of the 365 Songs of the Century bearing the most historical significance. It earned a Grammy Hall of Fame Award and an induction into the Rock and Roll Hall of Fame's 500 Songs that Shaped Rock and Roll. A UK survey conducted by the Guinness World Records British Hit Singles Book named it the second best single of all time, while Rolling Stone ranked it number three in their list of "The 500 Greatest Songs of All Time". Since 2005, event organisers have played it just before the New Year's Times Square Ball drops in New York City. Dozens of artists have performed or recorded versions of "Imagine", including Madonna, Stevie Wonder, Joan Baez, Lady Gaga, Elton John and Diana Ross. Emeli Sandé recorded a cover for the BBC to use during the end credits montage at the close of the 2012 Summer Olympics coverage in August 2012. "Imagine" subsequently re-entered the UK Top 40, reaching number 18. 
Question: What are the first names of the people who co-produced Imagine with Specter?

SOLUTION: Yoko.

PROBLEM: Passage: The boar was an important symbol in prehistoric Europe, where, according to the archaeologist Jennifer Foster, it was "venerated, eulogised, hunted and eaten ... for millennia, until its virtual extinction in recent historical time." Anglo-Saxon boar symbols follow a thousand years of similar iconography, coming after La Tène examples in the fourth century BC, Gaulish specimens three centuries later, and Roman boars in the fourth century AD. They likely represent a fused tradition of European and Mediterranean cultures. The boar is said to have been sacred to a mother goddess figure among linguistically Celtic communities in Iron Age Europe, while the Roman historian Tacitus, writing around the first century AD, suggested that the Baltic Aesti wore boar symbols in battle to invoke her protection.Boar-crested helmets are depicted on the turn-of-the-millennium Gundestrup cauldron, discovered in Denmark, and on a Torslunda plate from Sweden, made some 500 years later. Though the Romans also included the boar in their stable of symbols—four legions, including the twentieth, adopted it as their emblem—it was only one among many. The boar nonetheless persisted in continental Germanic tradition during the nearly 400 years of Roman rule in Britain, such as in association with the Scandinavian gods Freyja and Freyr. Its return to prominence in the Anglo-Saxon period, as represented by the boars from Benty Grange, Wollaston, Guilden Morden, and Horncastle, may therefore suggest the post-Roman reintroduction of a Germanic tradition from Europe, rather than the continuation of a tradition in Britain through 400 years of Roman rule. Whatever its precise symbolism, the Anglo-Saxon boar appears to have been associated with protection; the Beowulf poet makes this clear, writing that boar symbols on helmets kept watch over the warriors wearing them. 
Question: What is the precise name of that which likely represents a fused tradition of European and Mediterranean cultures?

SOLUTION: Anglo-Saxon boar symbols.

PROBLEM: 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?

SOLUTION:
Boult.
