Question: How many people were arrested in the Sonderaktion Krakau? Passage 1:The House of Aviz, known as the Joanine Dynasty, succeeded the House of Burgundy as the reigning house of the Kingdom of Portugal. The house was founded by John I of Portugal, who was the Grand Master of the Order of Aviz. When King John II of Portugal died without an heir, the throne of Portugal passed to his cousin, Manuel, Duke of Beja. When King Sebastian of Portugal died, the throne passed to his uncle, Henry of Portugal (he might be called Henry II because Henry, Count of Portugal, father of Alphonso I of Portugal, was the first of that name to rule Portugal). When Henry died, a succession crisis occurred and António, Prior of Crato, was proclaimed António of Portugal. 
 Passage 2:In what is considered by most historians as the greatest upset in the history of American presidential politics, Democratic incumbent President Harry S. Truman defeated Republican nominee Thomas E. Dewey. Going into Election Day, virtually every prediction (with or without public opinion polls) indicated that Truman would lose. Truman took most states outside the Northeast and Deep South, and won the popular vote by four points. Dewey won his party's nomination for the second straight election, defeating Ohio Senator Robert A. Taft and former Minnesota Governor Harold Stassen on the Republican convention's second ballot. Truman won the Democratic nomination on the first ballot, but the party's platform on civil rights caused a third party run by Dixiecrat Strom Thurmond, the Governor of South Carolina. Thurmond took four states in the Deep South. Former Vice President and former Democrat Henry A. Wallace ran as the Progressive nominee, but took only two percent of the popular vote.
 Passage 3:Witold Wilkosz was born on 14 August 1891 in Kraków to parents Jan, a Polish teacher, and Józefa née Vopalko. He showed a considerable talent for mathematics and languages since early childhood. He passed his final school-leaving Matura exam at the John III Sobieski High School (known in Poland as Gimnasium). He was a friend of fellow mathematician Stefan Banach. Before graduating from high school, he had written an article on semitology for which he was offered a scholarship and membership from Morgenländische Gesselchaft Scienctific Society, which enabled him to study at the University of Beirut. After a few months, he returned to Kraków and took up philology studies at the Jagiellonian University. After two years, he decided to change the course to mathematics, which he studied in Kraków and Turin. He received his doctoral degree on the basis of his dissertation on Lebesgue integrals and started to work as an academic teacher at his alma mater. In 1920, he obtained a habilitation and in 1936 he became a professor. He was arrested on 6 November 1939 by Nazi Germans alongside other prominent intellectuals and professors of Kraków in the infamous Sonderaktion Krakau. However, due to a serious illness, he was soon released together with nine other professors on 9 November. He returned home and began to work as a teacher. To supplement his income, he accepted another job at the Powszechny Zakład Ubezpieczeń Wzajemnych insurance company. In the following years, his health seriously deteriorated. He died of pneumonia on 31 March 1941.
