Question: How long was the Nazi Party around for before Stahlecker joined it? Passage:On 1 May 1932, Stahlecker joined the Nazi Party (no. 3,219,015) as well as the SS (no. 73,041). On 29 May 1933, he was appointed deputy director of the Political Office of the Wurttemberg State Police. In 1934, he was appointed head of the Gestapo in the German state of Wurttemberg and soon assigned to the main office of the Sicherheitsdienst (SD). On 11 May 1937, he became head of the Gestapo in Breslau. After the incorporation of Austria in 1938, Stahlecker became SD chief of the Danube district (Vienna), a post he retained even after being promoted to SS-Standartenfuhrer. In the summer of 1938, Stahlecker became Inspector of the Security Police in Austria, succeeding Gestapo chief Heinrich Muller in that position. As of 20 August 1938, Stahlecker was the formal head of the Central Agency for Jewish Emigration in Vienna, though its de facto leader was Adolf Eichmann. Differences of opinion with Reinhard Heydrich motivated Stahlecker to move to the Auswartiges Amt (Foreign Office), after which he held posts as the commander of the Security Police and SD in the Protectorate of Bohemia and Moravia under SS-Brigadefuhrer Karl Hermann Frank. In mid-October 1939, Eichmann and Stahlecker decided to begin implementation of the Nisko Plan.

Question: Who was the coach of the team Tony Craig played against in his first game in the first division? Passage:Born in Greenwich, London, Craig came through the youth ranks at Millwall. Adept as a central defender or a left back, he received his maiden call into the first team squad for a First Division league match against Bradford City on 5 April 2003 and was an unused substitute during the 10 win. Craig made his professional debut with a starting appearance in a 33 draw with Nottingham Forest on 26 April 2003 and lasted 67 minutes before being substituted for Robbie Ryan. He started in the final game of the 200203 season at home to Coventry City and scored the first senior goal of his career in the 20 win, with the opener on 51 minutes. Craig began the 200304 season as a virtual ever-present, making 10 appearances, but he dropped out of the squad entirely in October 2003. He was again out of favour with manager Dennis Wise during the 200405 season and had to wait until 19 February 2005 for his first appearance, which came with a start in a 10 defeat to Stoke City and he finished the campaign with 10 appearances.

Question: What year was the first issue of Gleason's comic that was selling a million copies a month by 1948? Passage:Following the postwar crime comics vogue spearheaded by publisher Lev Gleason's Crime Does Not Pay, which by 1948 was selling over a million copies a month, came romance comics, which by 1949 outsold all other genres, and horror comics. The same month in which Adventures into the Unknown premiered, the comic-book company EC, which would become the most prominent horror-comics publisher of the 1950s, published its first horror story, "Zombie Terror", by the then relatively unknown writer and artist Johnny Craig, in the superhero comic Moon Girl #5. Almost simultaneously,Trans-World Publications issued its one-and-only comic, the one-shot Mysterious Traveler Comics #1 (November 1948), based on the Mutual Broadcasting Network's radio show of that name and including amid its crime and science-fiction stories a reprint of the Edgar Allan Poe adaptation "The Tell Tale Heart", reprinted from Charlton Comics' Yellowjacket Comics #6. Street and Smith also published two issues of "Ghost Breakers" in late 1948. (ibid GCDB)
