Final answer:
The barrack for medical procedures was the most feared in concentration camps due to the inhumane medical experiments conducted there. Auschwitz had such barracks and was the largest and most notorious of all death camps.
Step-by-step explanation:
The barrrack for medical procedures was one of the most feared locations in the concentration camps during World War II. This is because these barracks were often the sites of brutal medical experiments carried out by Nazi doctors. Victims of these medical experiments were subject to immense pain, suffering, and often death without any form of anesthesia or consent. These experiments included everything from testing the limits of human endurance to deliberate infections with deadly diseases.
Auschwitz, the largest of the death camps and notorious for its brutality, had its own series of medical experimentation barracks where prisoners were subjected to horrific experiments. Moreover, in the extermination camps, people were sent primarily to be killed immediately upon arrival, which differentiates the function of the barracks in extermination camps from the rest of the concentration camp system.
