question:
Who thought the pope was fallible?, Context: In January 1519, at Altenburg in Saxony, the papal nuncio Karl von Miltitz adopted a more conciliatory approach. Luther made certain concessions to the Saxon, who was a relative of the Elector, and promised to remain silent if his opponents did. The theologian Johann Eck, however, was determined to expose Luther's doctrine in a public forum. In June and July 1519, he staged a disputation with Luther's colleague Andreas Karlstadt at Leipzig and invited Luther to speak. Luther's boldest assertion in the debate was that Matthew 16:18 does not confer on popes the exclusive right to interpret scripture, and that therefore neither popes nor church councils were infallible. For this, Eck branded Luther a new Jan Hus, referring to the Czech reformer and heretic burned at the stake in 1415. From that moment, he devoted himself to Luther's defeat.
answer:
Luther


question:
What had kept egyptian citizens poor before Nasser?, Context: Nasser made Egypt fully independent of British influence, and the country became a major power in the developing world under his leadership. One of Nasser's main domestic efforts was to establish social justice, which he deemed a prerequisite to liberal democracy. During his presidency, ordinary citizens enjoyed unprecedented access to housing, education, jobs, health services and nourishment, as well as other forms of social welfare, while feudalistic influence waned. By the end of his presidency, employment and working conditions improved considerably, although poverty was still high in the country and substantial resources allocated for social welfare had been diverted to the war effort.
answer:
feudalistic influence


question:
Who didn't believe in the implosion concept?, 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".
answer:

many of his colleagues
