Problem: Background: The Beatles were an English rock band formed in Liverpool in 1960. With members John Lennon, Paul McCartney, George Harrison and Ringo Starr, they became widely regarded as the foremost and most influential music band. Rooted in skiffle, beat and 1950s rock and roll, the Beatles later experimented with several musical styles, ranging from pop ballads and Indian music to psychedelia and hard rock, often incorporating classical elements and unconventional recording techniques in innovative ways. In 1963 their enormous popularity first emerged as "Beatlemania"; as the group's music grew in sophistication, led by primary songwriters Lennon and McCartney, the band were integral to pop music's evolution into an art form and to the development of the counterculture of the 1960s.
Context: In Icons of Rock: An Encyclopedia of the Legends Who Changed Music Forever, Scott Schinder and Andy Schwartz describe the Beatles' musical evolution: In their initial incarnation as cheerful, wisecracking moptops, the Fab Four revolutionised the sound, style, and attitude of popular music and opened rock and roll's doors to a tidal wave of British rock acts. Their initial impact would have been enough to establish the Beatles as one of their era's most influential cultural forces, but they didn't stop there. Although their initial style was a highly original, irresistibly catchy synthesis of early American rock and roll and R&B, the Beatles spent the rest of the 1960s expanding rock's stylistic frontiers, consistently staking out new musical territory on each release. The band's increasingly sophisticated experimentation encompassed a variety of genres, including folk-rock, country, psychedelia, and baroque pop, without sacrificing the effortless mass appeal of their early work. In The Beatles as Musicians, Walter Everett describes Lennon and McCartney's contrasting motivations and approaches to composition: "McCartney may be said to have constantly developed - as a means to entertain - a focused musical talent with an ear for counterpoint and other aspects of craft in the demonstration of a universally agreed-upon common language that he did much to enrich. Conversely, Lennon's mature music is best appreciated as the daring product of a largely unconscious, searching but undisciplined artistic sensibility." Ian MacDonald describes McCartney as "a natural melodist - a creator of tunes capable of existing apart from their harmony". His melody lines are characterised as primarily "vertical", employing wide, consonant intervals which express his "extrovert energy and optimism". Conversely, Lennon's "sedentary, ironic personality" is reflected in a "horizontal" approach featuring minimal, dissonant intervals and repetitive melodies which rely on their harmonic accompaniment for interest: "Basically a realist, he instinctively kept his melodies close to the rhythms and cadences of speech, colouring his lyrics with bluesy tone and harmony rather than creating tunes that made striking shapes of their own." MacDonald praises Harrison's lead guitar work for the role his "characterful lines and textural colourings" play in supporting Lennon and McCartney's parts, and describes Starr as "the father of modern pop/rock drumming".
Question: How did they develop their style?
Answer: Although their initial style was a highly original, irresistibly catchy synthesis of early American rock and roll

Problem: Background: George Edward Foreman (born January 10, 1949) is an American former professional boxer who competed from 1969 to 1977, and from 1987 to 1997. Nicknamed "Big George", he is a two-time world heavyweight champion and an Olympic gold medalist. Outside the sport he is an ordained minister, author, and entrepreneur. After a troubled childhood Foreman took up amateur boxing and won a gold medal in the heavyweight division at the 1968 Summer Olympics.
Context: In 1972, still undefeated and with an impressive knockout record, Foreman was set to challenge undefeated and Undisputed World Heavyweight Champion Joe Frazier. Despite boycotting a title elimination caused by the vacancy resulting from the championship being stripped from Muhammad Ali, Frazier had won the title from Jimmy Ellis and defended his title four times since, including a 15-round unanimous decision over the previously unbeaten Ali in 1971 after Ali had beaten Oscar Bonavena and Jerry Quarry. Despite Foreman's superior size and reach, he was not expected to beat Frazier and was a 3:1 underdog going into the fight. The Sunshine Showdown took place on January 22, 1973, in Kingston, Jamaica, with Foreman dominating the fight to win the championship by technical knockout. In ABC's re-broadcast, Howard Cosell made the memorable call, "Down goes Frazier! Down goes Frazier! Down goes Frazier!" Before the fight Frazier was 29-0 (25 KO) and Foreman was 37-0 (34 KO). Frazier was knocked down six times by Foreman within two rounds (the three-knockdown rule was not in effect for this bout). After the second knockdown, Frazier's balance and mobility were impaired to the extent that he was unable to evade Foreman's combinations. Frazier managed to get to his feet for all six knockdowns, but referee Arthur Mercante eventually called an end to the one-sided bout. Foreman was sometimes characterized by the media as an aloof and antisocial champion. According to them, he always seemed to wear a sneer and was not often available to the press. Foreman later attributed his demeanor during this time as an emulation of Sonny Liston, for whom he had been an occasional sparring partner. Foreman defended his title successfully twice during his initial reign as champion. His first defense, in Tokyo, pitted him against Puerto Rican Heavyweight Champion Jose Roman. Roman was not regarded as a top contender, and it took Foreman only 2 minutes to end the fight, one of the fastest knockouts in a Heavyweight Championship bout.
Question: Did he win by knock out?
Answer:
dominating the fight to win the championship by technical knockout.
