[Q]: Question: "What earned him his doctorate?"  Context: "Since there were few posts in Hungary for mathematicians, and those were not well-paid, his father wanted von Neumann to follow him into industry and therefore invest his time in a more financially useful endeavor than mathematics. So it was decided that the best career path was to become a chemical engineer. This was not something that von Neumann had much knowledge of, so it was arranged for him to take a two-year non-degree course in chemistry at the University of Berlin, after which he sat the entrance exam to the prestigious ETH Zurich, which he passed in September 1923. At the same time, von Neumann also entered Pázmány Péter University in Budapest, as a Ph.D. candidate in mathematics. For his thesis, he chose to produce an axiomatization of Cantor's set theory. He passed his final examinations for his Ph.D. soon after graduating from ETH Zurich in 1926. He then went to the University of Göttingen on a grant from the Rockefeller Foundation to study mathematics under David Hilbert."  Answer:
****
[A]: he chose to produce an axiomatization of Cantor's set theory


[Q]: Question: "Who handles the finances of a political party?"  Context: "A political party is typically led by a party leader (the most powerful member and spokesperson representing the party), a party secretary (who maintains the daily work and records of party meetings), party treasurer (who is responsible for membership dues) and party chair (who forms strategies for recruiting and retaining party members, and also chairs party meetings). Most of the above positions are also members of the party executive, the leading organization which sets policy for the entire party at the national level. The structure is far more decentralized in the United States because of the separation of powers, federalism and the multiplicity of economic interests and religious sects. Even state parties are decentralized as county and other local committees are largely independent of state central committees. The national party leader in the U.S. will be the president, if the party holds that office, or a prominent member of Congress in opposition (although a big-state governor may aspire to that role). Officially, each party has a chairman for its national committee who is a prominent spokesman, organizer and fund-raiser, but without the status of prominent elected office holders."  Answer:
****
[A]: treasurer


[Q]: Question: "What is the range of hues for a person that can be referred to as a ginger?"  Context: "Red hair varies from a deep burgundy through burnt orange to bright copper. It is characterized by high levels of the reddish pigment pheomelanin (which also accounts for the red color of the lips) and relatively low levels of the dark pigment eumelanin. The term redhead (originally redd hede) has been in use since at least 1510. Cultural reactions have varied from ridicule to admiration; many common stereotypes exist regarding redheads and they are often portrayed as fiery-tempered. (See red hair)."  Answer:
****
[A]: deep burgundy through burnt orange to bright copper


[Q]: Question: "Who published a book in 1997?"  Context: "In his book, Humanism (1997), Tony Davies calls these critics "humanist anti-humanists". Critics of antihumanism, most notably Jürgen Habermas, counter that while antihumanists may highlight humanism's failure to fulfil its emancipatory ideal, they do not offer an alternative emancipatory project of their own. Others, like the German philosopher Heidegger considered themselves humanists on the model of the ancient Greeks, but thought humanism applied only to the German "race" and specifically to the Nazis and thus, in Davies' words, were anti-humanist humanists. Such a reading of Heidegger's thought is itself deeply controversial; Heidegger includes his own views and critique of Humanism in Letter On Humanism. Davies acknowledges that after the horrific experiences of the wars of the 20th century "it should no longer be possible to formulate phrases like 'the destiny of man' or the 'triumph of human reason' without an instant consciousness of the folly and brutality they drag behind them". For "it is almost impossible to think of a crime that has not been committed in the name of human reason". Yet, he continues, "it would be unwise to simply abandon the ground occupied by the historical humanisms. For one thing humanism remains on many occasions the only available alternative to bigotry and persecution. The freedom to speak and write, to organise and campaign in defence of individual or collective interests, to protest and disobey: all these can only be articulated in humanist terms.""  Answer:
****
[A]:
Tony Davies
