question:
Question: What was the original name of the Suzba Bezpieczenstwa? Passage:On 30 June 1943 he was arrested by the Gestapo in Warsaw and sent to Berlin. Rowecki was arrested due to his betrayal by Ludwik Kalkstein "Hanka", Eugeniusz Swierczewski "Genes" and Blanka Kaczorowska "Sroka" who were Gestapo agents. All of them were members of the Home Army but in fact collaborated with the Gestapo. Swierczewski, Kalkstein and Kaczorowska were sentenced to death for high treason by the Secret War Tribunal of the Polish Secret State. The sentence on Eugeniusz Swierczewski was carried out by troops commanded by Stefan Rys ("Jozef"). They hanged Swierczewski in the basement of the house at 74 Krochmalna Street in Warsaw. Kalkstein received protection from the Gestapo and was not harmed. He fought in a Waffen SS unit during the Warsaw Uprising of 1944 under the name of Konrad Stark. After the war, he worked for the Polish Radio station in Szczecin and was later recruited as an agent by the Urzad Bezpieczenstwa. In 1982, he emigrated to France; he died in 1994. Blanka Kaczorowska also survived the war. Her death sentence was not carried out because she was pregnant. After the war, she also worked as a secret agent for the Urzad Bezpieczenstwa and later for the renamed Suzba Bezpieczenstwa. She emigrated to France in 1971. She died in 2002

question:
Question: Did the highest scoring fighter ace have any siblings? Passage:After a short rest, the 90th continued across the Moselle River to take Mainz, 22 March, and crossed the rivers Rhine, the Main, and the Werra in rapid succession. Pursuit continued to the Czech border, 18 April 1945, and into the Sudetes mountain range. The division was en route to Prague when they came upon the remaining 1500 emaciated prisoners left behind by the SS at Flossenburg concentration camp. Today, a memorial wall at the former camp honors the 90th as the liberators of Flossenburg concentration camp. A week later, word came that the war in Europe ended on 8 May 1945. On that same day, Erich Hartmann, the highest-scoring fighter ace in history, along with a squadron of the elite Jagdgeschwader 52 fighter wing (the highest-scoring fighter wing in history), surrendered to the 90th.

question:
Question: When did the battle for which Vittorio Veneto is named begin? Passage:Vittorio Veneto was ordered under the 1934 construction program, and was named for the Battle of Vittorio Veneto, a decisive Italian victory over the Austro-Hungarian Empire in OctoberNovember 1918 during World War I. Her keel was laid on 28 October 1934 at Cantieri Riuniti dell'Adriatico in Trieste, the same day as her sister ship . Vittorio Veneto was launched on 25 July 1937, and major construction was completed by October 1939. The fitting-out process was greatly delayed due to repeated changes to the design and shortages of heavy armor plate. Before she could begin sea trials, Vittorio Veneto was moved to Venice on 4 October to have her bottom cleaned of the fouling that had accumulated during the long fitting-out period, since the Venice Arsenal had the only drydock in Italy long enough to accommodate a ship the size of the Littorio class.
