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 Ustaše regime. Nazi secret police, Gestapo, took over Sajmište. 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 Sajmište 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 Gradiška concentration camps run by ISC Croatian Ustaše. Partisans captured throughout Serbia were also sent to Sajmište. 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 Sajmište on 17 April 1944, killing some 100 inmates and inflicting heavy damage on the camp itself, destroying all the buildings except for the Spasić pavilion and the Central tower..

Question: Question: What is the peak elevation of the mountain range that Poxte is part of? Passage:Poxte is a river and valley of the Maya Mountains in Guatemala. The valley is noted for numerous Maya sites such as Ixtutz and the Petén Caves. The river is located on the southwest of the Dolores plateau and northwest of Poptún, in the Guatemalan department of Petén. The source of the river is on the same plateau, near the villages of Boca del Monte and Santo Domingo. The river flows westwards through the hamlet of Poxte, it then disappears amongst the karst topography and resumes its course to the west. It continues westwards into the San Juan River, which is a tributary of the Machaquila River. The Machaquila River feeds into the Pasión River, which flows into the Usumacinta River and into the Gulf of Mexico. The upper reaches of the Poxte River shares its drainage with the Mopan River, which flows eastwards into the Caribbean Sea.
