Final answer:
Concentration camps during the Holocaust had dual roles: education and indoctrination, as well as extermination and forced labor.
Step-by-step explanation:
The dual roles of concentration camps during the Holocaust were that they served as sites for education and indoctrination, as well as sites for extermination and forced labor.
First, concentration camps were used to indoctrinate prisoners with Nazi ideology through propaganda, forced labor, and brutal treatment. The goal was to break the spirit of the prisoners and make them compliant to the Nazi regime.
Second, concentration camps were used as extermination centers where millions of people, primarily Jews, were systematically killed in gas chambers and through other inhumane methods.
