Extract the answer to the question from the following context. Question: His schooling was completed in what? 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.

Extract the answer to the question from the following context. Question: What did von Neumann's design do? Context: Von Neumann's principal contribution to the atomic bomb was in the concept and design of the explosive lenses needed to compress the plutonium core of the Fat Man weapon that was later dropped on Nagasaki. While von Neumann did not originate the "implosion" concept, he was one of its most persistent proponents, encouraging its continued development against the instincts of many of his colleagues, who felt such a design to be unworkable. He also eventually came up with the idea of using more powerful shaped charges and less fissionable material to greatly increase the speed of "assembly".

Extract the answer to the question from the following context. Question: \What occupation does the court case revolve around? Context: In April 2009, the United States Supreme Court agreed to hear a suit over reverse discrimination brought by 18 white firefighters against the city. The suit involved the 2003 promotion test for the New Haven Fire Department. After the tests were scored, no black firefighters scored high enough to qualify for consideration for promotion, so the city announced that no one would be promoted. In the subsequent Ricci v. DeStefano decision the court found 5-4 that New Haven's decision to ignore the test results violated Title VII of the Civil Rights Act of 1964. As a result, a district court subsequently ordered the city to promote 14 of the white firefighters.
