Answer:
They divided the groups into two. Who could work and not.
Step-by-step explanation:
When the prisoners would get to Auschwitz, the women with children or pregnant would go off to a line with elders and would go off into the ovens. They would not be fit for work and they were no use to the German cause. The men, and sometimes able women, would go off into two other lines, seprated by gender to the barracks where they would spend their days working as slaves for the Germans.
