[EX Q]: Question: How many siblings did Khalid have in total? Passage:Khalid was a member of the Shayban tribe, dominant in the region of Diyar Bakr in the northern Jazira, and third son of Yazid ibn Mazyad al-Shaybani, who served twice as Arab governor (ostikan) of Arminiya (a large province encompassing the whole of Transcaucasia). Khalid served in the same office no less than four times: in 813/814, 828–832, briefly in 841 and again under Caliph al-Wathiq (r. 842–845). In his first tenure, he showed himself conciliatory towards the native Christian population and the nakharar princes, but his second tenure was marked by the brutal suppression of several revolts by local Arab magnates, as well as the harsh treatment of the Christian population. As a result, when his re-appointment to the office was announced in 841, a rebellion broke out, forcing the Abbasid government to recall him immediately. Nevertheless, al-Wathiq assigned Arminiya to Khalid. The latter arrived in the province at the head of an army, and crushed any opposition. He died soon after at Dvin, where he was buried. He was succeeded by his son, Muhammad. His younger son Haytham ibn Khalid ruled in the family's stronghold of Shirvan, and was the first to claim the title of Shirvanshah.

[EX Q]: 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 Urząd Bezpieczeństwa. 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 Urząd Bezpieczeństwa and later for the renamed Służba Bezpieczeństwa. She emigrated to France in 1971. She died in 2002

[EX Q]: Question: How old was the prime minister of the puppet government installed by the Axis? Passage:Mušicki was stationed in Slavonski Brod at the time of the Axis invasion of Yugoslavia in April 1941 and served as the Royal Yugoslav Army commander responsible for the railroad between Belgrade and Zagreb in the rank of colonel. He demonstrated his support for the Germans by helping their forces during the invasion. Yugoslavia was quickly conquered by the Axis powers and Mušicki remained in Slavonski Brod for several months after the conquest. He attempted to join the Ustaše Militia there, but was rejected. He went to Belgrade in mid-August, where he was received by Zbor leader Dimitrije Ljotić. On 6 October, Milan Nedić, the Prime Minister of the Axis-installed puppet Government of National Salvation, appointed Mušicki to lead the Serbian Volunteer Command (, SDK). Mušicki was involved in executing Serb civilians in the town of Čačak in December 1941. He and Milan Aćimović contacted Chetnik leader Draža Mihailović on 5 December, possibly in an effort to warn him in advance of the assault the Germans had planned, codenamed Operation Mihailovic. This action prompted the Germans to question Mušicki's loyalty. He was removed from command at the end of 1941 and imprisoned by the Germans, but was later freed at Nedić's intervention.
