Question: When was the organization where Ingold was made an officer in 1995 founded? Passage:He was born to Sir Christopher Ingold and Dr. Hilda Usherwood, and studied for a BSc in Chemistry at the University of London, completing his degree in 1949. He continued his higher education with a PhD in chemistry at Oxford University, which he completed in 1951. Soon after graduation he moved to Canada to begin work with the National Research Council, followed by two years of post-doctoral research at the University of British Columbia. He returned to work for the NRC in 1955 as a research officer, followed by a promotion to head of the Free Radical Chemistry Section. He was awarded the 1968 Petroleum Chemistry Award, the 1988 Linus Pauling Award, and both the Davy Medal and Royal Medal of the Royal Society, the latter for "elucidating the mechanism of reactions involving free radicals". In 1995 he was made an officer of the Order of Canada. He has received honorary degrees from the universities of Guelph, Mount Allison, St Andrews, Carleton, McMaster and Dalhousie.

Question: How old was the governor when Rosas was overthrown? Passage:The central figure in the overthrow of Rosas, Entre Ríos Governor Justo José de Urquiza, was granted the power of a head of state by the Palermo Protocols of April 6, 1852. This provoked resistance in Buenos Aires, however, which then refused to ratify the San Nicolás Agreement of May 31. The prospect of having the Argentine Congress headquartered in Santa Fe proved especially objectionable, and Urquiza's June 12 appointment of former President Vicente López y Planes failed to turn public opinion in Buenos Aires. Colonel Bartolomé Mitre rallied the Assembly against the San Nicolás Accords. The most contentious issue remained the Buenos Aires Customs, which remained under the control of the city government and was the chief source of public revenue. Nations with which the Confederation maintained foreign relations, moreover, kept all embassies in Buenos Aires (rather than in the capital, Paraná).

Question: In which country did Whittaker Chambers went to war as a U.S. Army Lieutenant? Passage:Novak was registered Democrat, despite his conservative political views. He held more centrist views in his early career, and he supported the Democratic presidential candidacies of John F. Kennedy and Lyndon B. Johnson, of whom he was a friend. In later years, he said that he maintained his registered Democratic status so he could vote in District of Columbia Democratic primaries where victory would be tantamount to election. He was also close friends with Everett Dirksen. Novak later stated that reading Whittaker Chambers' book Witness changed his views from moderate-to-liberal to a strident anticommunism. Reading Chambers' message as a U.S. Army lieutenant in the Korean War gave him a feeling of moral absolutism in his cause. Novak's views turned further rightward through the 1970s, but Novak remained strongly critical toward Ronald Reagan and his supply side economics in the early 1980s. Novak changed his mind after debating economics with Reagan face to face, and he later wrote that Reagan was one of the very few politicians that he ever respected.
