Answer:
Racism, laws, and social practices.
Step-by-step explanation:
Racism- the Germans treated the Jews differently- they didn’t let Jewish kids go to German schools- Jewish doctors and lawyers had their license taken away.
Laws- Jews were not allowed in parks or movie theaters- Jewish kids were not allowed in German schools.
Social practices- Many Germans stopped associating or “being friends” with Jews- Jews and non-Jewish Germans were not allowed to join the same clubs.
