Problem: Background: John Kenneth Galbraith (October 15, 1908 - April 29, 2006), also known as Ken Galbraith, was a Canadian-born economist, public official, and diplomat, and a leading proponent of 20th-century American liberalism. His books on economic topics were bestsellers from the 1950s through the 2000s, during which time Galbraith fulfilled the role of public intellectual. As an economist, he leaned toward post-Keynesian economics from an institutionalist perspective. Galbraith was a long-time Harvard faculty member and stayed with Harvard University for half a century as a professor of economics.
Context: In February 1946, Galbraith took a leave of absence from his magazine work for a senior position in the State Department as director of the Office of Economic Security Policy where he was nominally in charge of economic affairs regarding Germany, Japan, Austria, and South Korea. He was distrusted by the senior diplomats so he was relegated to routine work with few opportunities to make policy. Galbraith favored detente with the Soviet Union, along with Secretary of State James F. Byrnes and General Lucius D. Clay, a military governor of the US Zone in Germany from 1947 to 1949, but they were out of step with the containment policy then being developed by George Kennan and favored by the majority of the US major policymakers. After a disconcerting half-year, Galbraith resigned in September 1946 and went back to his magazine writing on economics issues. Later, he immortalized his frustration with "the ways of Foggy Bottom" in a satirical novel, The Triumph (1968). The postwar period also was memorable for Galbraith because of his work, along with Eleanor Roosevelt and Hubert Humphrey, to establish a progressive policy organization Americans for Democratic Action (ADA) in support of the cause of economic and social justice in 1947. During his time as an adviser to President John F. Kennedy, Galbraith was appointed United States Ambassador to India from 1961 to 1963. His rapport with President Kennedy was such that he regularly bypassed the State Department and sent his diplomatic cables directly to the president. In India, he became a confidant of Prime Minister Jawaharlal Nehru and extensively advised the Indian government on economic matters. In 1966, when he was no longer ambassador, he told the United States Senate that one of the main causes of the 1965 Kashmir war was American military aid to Pakistan. While in India, he helped establish one of the first computer science departments, at the Indian Institute of Technology in Kanpur, Uttar Pradesh. Even after leaving office, Galbraith remained a friend and supporter of India. Because of his recommendation, First Lady of the United States Jacqueline Bouvier Kennedy undertook her 1962 diplomatic missions in India and Pakistan. In autumn 1972 Galbraith was an adviser and assistant to Nixon's rival candidate George McGovern in the election campaign for the American presidency. During this time (September 1972) he travelled in to China in his role as president of the American Economic Association (AEA) at the invitation of Mao Zedong's communist government with the economists Leontief and Tobin and in 1973 published an account of his experiences in A China Passage. Galbraith wrote that there was "no serious doubt that China is devising a highly effective economic system," "[d]issidents are brought firmly into line in China, but, one suspects, with great politeness," "Greater Shanghai ... has a better medical service than New York," and considered it not implausible that Chinese industrial and agricultural output was expanding annually at a rate of 10 to 11%.

Problem: Background: At the Drive-In is an American post-hardcore band from El Paso, Texas, formed in 1994. The band currently consists of Cedric Bixler (vocals), Omar Rodriguez (guitar, vocals), Paul Hinojos (bass), Tony Hajjar (drums) and Keeley Davis (guitar, vocals). After several early line-up changes, the band solidified into a five-piece, consisting of Bixler, Rodriguez, Jim Ward, Hinojos and Hajjar. At the Drive-In released three studio albums and five EPs before breaking up in 2001.
Context: On November 12, 2000, At the Drive-In was involved in a motor vehicle accident when their touring van skidded out of control on ice and flipped onto its roof. Though the accident left the band shaken, none of the members sustained serious injury - Hajjar and Bixler-Zavala were taken to the hospital for minor injuries and released. In January 2001, At the Drive-In traveled to Australia for the Big Day Out music festival. While performing in Sydney, they left partway through their set after telling the attendance to calm down and observe the safety rules against moshing. After the refusal of the crowd, frontman Cedric Bixler-Zavala told them "You're a robot, you're a sheep!" and bleated at them several times before the band left the stage after performing only three songs. "I think it's a very, very sad day when the only way you can express yourself is through slam-dancing," he proclaimed. The following month, At the Drive-In cancelled the last five dates of its European tour, citing "complete mental and physical exhaustion" of the members. In March 2001--less than a month away from a United States tour set to commence on April 14--at the peak of their popularity and following a world tour, At the Drive-In broke up, initially referring to the split as an "indefinite hiatus." The band played their last show at Groningen's Vera venue on February 21, 2001. A combination of excessive hype, relentless touring, artistic differences, and Rodriguez-Lopez and Bixler-Zavala's drug habits contributed to the demise of the band. Commenting on the hiatus, guitarist Rodriguez said: "After a non-stop six-year cycle of record/tour/record/tour, we are going on an indefinite hiatus. We need time to rest up and re-evaluate, just to be human beings again and to decide when we feel like playing music again." Cedric Bixler took responsibility for the breakup, saying repeatedly in interviews that he felt almost as if At the Drive-In was holding him back and that he didn't want his music to be confined to punk or hardcore -- that it should encompass many genres and be even more progressive, alternative, and "against-the-grain." Bixler-Zavala and Rodriguez-Lopez had stated that they wanted their next album to sound like Pink Floyd's The Piper at the Gates of Dawn, while the other members were intent on progressing in a more alternative rock direction.
