What was the purpose of Hitler's concentration camps? A. to educate German Jews in Nazi philosophy B. to train German youth to fight C. to provide a safe haven for those being persecuted by the Nazis D. to detain and kill Jews

D. To detain and kill Jews. Many were modified during the Second World War into what were then refereed to as "Death Camps", filled with gas chambers and ovens. The ovens were generally used for cremation of the masses of bodies executed using Zyklon B crystals of Cyanide in the chambers, but occasionally live people were tossed into the fires out of spite. Towards the end of the war the ovens were not used often as there was a severe fuel shortage. Instead, beams of wood were prepared before everyone's eyes for the thousands of people who would be burned at one time. There were segments of the camps designed specifically to serve as hospitals of experimentation where horrible experiments were performed on prisoners by individuals like Dr. Josef Mengele, Ilse Koch, and others. And it wasn't just Jewish people who were killed in the camps! Gays, Jehovah's Witnesses, Communists, and many Catholics who opposed Hitler were also thrown behind the barbed wire fences (which usually carried a 10,000 volt current).
