Question: Question: Who are the Gestapo? 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: What was the population of Rome during the last year that Lucius Sextius Lateranus served as a tribune of the plebs? Passage:The gens Sextia was a plebeian family at Rome, from the time of the early Republic and continuing into imperial times. The most famous member of the gens was Lucius Sextius Lateranus, who as tribune of the plebs from 376 to 367 BC, prevented the election of the annual magistrates, until the passage of the lex Licinia Sextia, otherwise known as the "Licinian Rogations," in the latter year. This law, brought forward by Sextius and his colleague, Gaius Licinius Calvus, opened the consulship to the plebeians, and in the following year Sextius was elected the first plebeian consul. Despite the antiquity of the family, only one other member obtained the consulship during the time of the Republic. Their name occurs more often in the consular fasti under the Empire.

Question: Question: When did the empire that could potentially invade the islands first experience military conflict with the United States? Passage:The military history of the Aleutian Islands began almost immediately following the purchase of Alaska from the Russian Empire by the United States in 1867. Prior to the early 20th century, the Aleutian Islands were essentially ignored by the United States Armed Forces, although the islands played a small role in the Bering Sea Arbitration when a number of British and American vessels were stationed at Unalaska to enforce the arbitrators' decision. By the early 20th century, a number of war strategies examined the possibility of conflict breaking out between the Empire of Japan and the United States. While the Aleutian Islands were seen as a potential staging point for invasions by either side, this possibility was dismissed owing to the islands' dismal climate. In 1922, the Washington Naval Treaty was signed, after which the United States Navy began to take an interest in the islands. However, nothing of significance was to materialize until World War II.
