Solution:
Many people in Germany in the 1940s believed in the Nazi ideology. The native Germans used to exploit the non-Germans. If anyone in their neighbourhood did not belong to the Aryan race, they used to mistreat them. The Nazis considered themselves as a superior race.However, not everyone was in support of Nazi Germany. Some people used to live in Nazi Germany but were not native Germans. Many of them were gipsies and blacks. Many natives of Germany did not support the Nazi ideology and did not consider Hitler as their saviour.
Hence, both the Assertion and Reason statements are true, but the Reason is not the correct explanation of the Assertion.
