Question: Question: Which day in April did Germany and its allies occupy and partition the Kingdom of Yugoslavia? Passage:After the April war of 1941 when Germany and its allies occupied and partitioned the Kingdom of Yugoslavia, entire Syrmia region (including the left bank of the Sava) became part of the Independent State of Croatia where they set the Ustase regime. Nazi secret police, Gestapo, took over Sajmiste. They encircled it with several rings of barbed wire turning it into what they referred to as "collection center" a euphemism for a prison. It eventually became a concentration camp. Until May 1942 Germans used Sajmiste concentration camp to mostly kill off Jews from Belgrade and other parts of Serbia. From April 1942 onwards, Serbian prisoners were transported in from Jasenovac and Stara Gradiska concentration camps run by ISC Croatian Ustase. Partisans captured throughout Serbia were also sent to Sajmiste. Detainees were also sent in from other parts of Yugoslavia, especially Serbs after major German offensives on briefly liberated territories. Executions of captured prisoners lasted as long as the camp existed. During their heavy "Easter bombing" of Belgrade, Allied aircraft bombed Sajmiste on 17 April 1944, killing some 100 inmates and inflicting heavy damage on the camp itself, destroying all the buildings except for the Spasic pavilion and the Central tower..

Question: Question: How many soldiers fought under the combined Cossack-Tatar side under chief Asand Demko? Passage:He began his studies in Poland and continued his education at the University of Leuven. His considerable wealth enabled him to establish his own private army, which suppressed Cossack riots and Tatar raids in Ukraine. In 1635 he became the first voivode of the Czernihow Voivodship. In 1646 he was appointed Field Crown Hetman. During the Khmelnytsky Uprising, he was captured by the Tatars after the Battle of Korsun in 1648. He was a prisoner-of-war until 1650 when he was ransomed. On 12 May 1651 he commanded victorious Polish army in the Battle of Kopyczynce between Poles and combined Cossack-Tatar forces under chief Asand Demko. In 1651, during the subsequent hostilities between the Commonwealth and Cossack-Tatar alliance, he was the nominal commander of the Polish army right wing at the great victorious Battle of Beresteczko (de facto commanded Jeremi Wisniowiecki). Upon death of Grand Crown Hetman Mikoaj Potocki, who was his political and personal adversary, hetman Kalinowski commanded the choicest elements of the Commonwealth army and he had at the camp at Batoh about 1012,000 soldiers and 1015,000 servants and camp followers. This army was surprised by the combined Cossack-Tatar army, consequently defeated and then capture of Polish soldiers and servants resulted in a wholesale slaughter of the best elements of Commonwealth army and their retinues, the event known as Battle of Batoh. Hetman was killed on 2 June 1652, during the last day of the battle, when trying to escape from the Cossack-Tatars-filled burning Polish camp, in woods some 3 kilometers from the Polish camp. Hetman's severed head was carried around the Cossack-Tatar camps, allegedly by the Nuredin-Sultan himself.

Question: Question: When did the place that inspired David Cohen to write "Lisa the Skeptic" first open? Passage:"Lisa the Skeptic" is the eighth episode of The Simpsons' ninth season. It first aired on the Fox network in the United States on November 23, 1997. On an archaeological dig with her class, Lisa discovers a skeleton that resembles an angel. All of the townspeople believe that the skeleton actually came from an angel, but skeptical Lisa attempts to persuade them that there must be a rational scientific explanation. The episode's writer, David X. Cohen, developed the idea after visiting the American Museum of Natural History, and decided to loosely parallel themes from the Scopes Monkey Trial. The episode also makes allusions to actual hoaxes, such as the Cardiff Giant.
