Answer: 1. Experimentation
2. Labour
Explanation: The Nazis committed a lot of crimes against the imprisoned Jews. The Imprisoned Jews were made to work as helpers in the houses of the lieutenants and the Generals of the Nazi army. They were shot immediately if they refused to work. They were not allowed inside the houses of these Generals. While women were made to work as helpers to the needs of the army men.
The imprisoned Jews were also used to do experiments upon. There were a lot of experiments conducted in the camps to help Axis soldiers survive in the field. To find the highest height from which the crews of damaged aircraft could parachute to safety, for instance, doctors from the German air force and the German Experimental Institution for Aviation carried out high-altitude studies on inmates at Dachau. In order to develop a successful hypothermia treatment, scientists conducted so-called freezing experiments on convicts. Prisoners were also employed to test a variety of seawater tainting techniques.
The most notorious were Josef Mengele's experiments at Auschwitz on twins of all ages. Along with Werner Fischer in Sachsenhausen, he also oversaw trials on Roma (Gypsies) to examine how various "races" fared against various communicable diseases. The goal of August Hirt's research at Strasbourg University was to prove "Jewish racial inferiority." A series of sterilization operations, mostly carried out in Auschwitz and Ravensbrück, were among the other horrifying procedures carried out to achieve Nazi racial ambitions. Scientists experimented with a variety of techniques in an effort to create a quick and affordable way for sterilizing large numbers of Jews, Roma, and other ethnic or genetically undesirable populations.
