Definition: Compose a new way to ask the same question. The new question must be asking the exact same thing as the original question does. Without any other information, you should be able to tell that the original question and the new question are the same. Preserve bracketed phrases in your new question. You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.

auxiliary information: Auschwitz concentration camp was a network of German Nazi concentration camps and extermination camps built and operated by the Third Reich in Polish areas annexed by Nazi Germany during World War II. It consisted of Auschwitz I, Auschwitz II‚ÄìBirkenau, Auschwitz III‚ÄìMonowitz, and 45 satellite camps. Auschwitz I was first constructed to hold Polish political prisoners, who began to arrive in May 1940. The first extermination of prisoners took place in September 1941, and Auschwitz II‚ÄìBirkenau went on to become a major site of the Nazi "Final Solution to the Jewish question". From early 1942 until late 1944, transport trains delivered Jews to the camp's gas chambers from all over German-occupied Europe, where they were killed with the pesticide Zyklon B. At least 1.1 million prisoners died at Auschwitz, around 90 percent of them Jewish; approximately 1 in 6 Jews killed in the Holocaust died at the camp. Others deported to Auschwitz included 150,000 Poles, 23,000 Romani and Sinti, 15,000 Soviet prisoners of war, 400 Jehovah's Witnesses, homosexuals, and tens of thousands of people of diverse nationalities.
