Many Jews, especially in eastern Europe, were centralized in ghettos, sometimes for years, prior to being deported to forced labor, concentration camps, and killing centers. What was the reason for centralizing Jews in ghettos?
1) To isolate and segregate Jews from the rest of the population
2) To provide a temporary living space for Jews
3) To protect Jews from persecution
4) To facilitate the deportation of Jews to forced labor, concentration camps, and killing centers
