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%.
Question: What did he do after he worked there?
Answer: Galbraith resigned in September 1946 and went back to his magazine writing on economics issues.

Problem: Background: Michael Bloomberg was born at St. Elizabeth's Hospital, in the Brighton neighborhood of Boston, on February 14, 1942. Bloomberg's family is Jewish. Bloomberg's father, William Henry Bloomberg (1906-1963), was born in Chelsea, Massachusetts and worked as an accountant for a dairy company. He was the son of Alexander "Elick" Bloomberg, an immigrant from Russia.
Context: During his second term as the mayor of New York City, Bloomberg unveiled PlaNYC: A Greener, Greater New York on April 22, 2007, to fight global warming, protect the environment and prepare for the projected 1 million additional people expected to be living in the city by the year 2030.  Under PlaNYC, in just 6 years New York City reduced citywide greenhouse gas emissions by 19% since 2005 and was on track to achieve a 30% reduction ahead of the PlaNYC 2030 goal. In October 2007 as part of PlaNYC, Bloomberg launched the Million Trees NYC initiative, which aimed to plant and care for one million trees throughout the city in the next decade. In November 2015, New York City planted its one millionth tree, two years ahead of the original 10-year schedule.  In 2008, Bloomberg convened the New York City Panel on Climate Change (NPCC), an effort to prepare the city for climate change. In 2012, Travel + Leisure readers voted New York City the "Dirtiest American City," for having the most extant litter. Bloomberg has been involved in motivating other cities to make changes and has spoken about reducing carbon dioxide emissions, using cleaner and more efficient fuels, using congestion pricing in New York City, and encouraging public transportation.  Bloomberg unveiled the Special Initiative for Rebuilding and Resiliency (SIRR) in June 2013, after the city was affected by Hurricane Sandy in October 2012. The $20-billion initiative laid out extensive plans to protect New York City against future the impacts of climate change. On September 26, 2013, Bloomberg announced that his administration's air pollution reduction efforts had resulted in the best air quality in New York City in more than 50 years. The majority of the air quality improvement was attributed to the phasing out of heavy polluting heating oils through New York's "Clean Heat" program. As a result of the improved air quality, the average life expectancy of New Yorkers had increased three years during Bloomberg's tenure, compared to 1.8 years in the rest of the country.
