Question

the nazi party adopted official anti - semitic policies because party members
hoped to encourage jewish people to emigrate from other places.
blamed jewish people for the many problems in the country.
wanted to prevent jewish people from leaving the country.
wished to get jewish support for the new government.

Explanation:

The Nazi Party's anti - Semitic policies were rooted in their scapegoating of Jewish people. They propagated the idea that Jewish people were responsible for Germany's economic, social, and political problems after World War I and during the Great Depression. The first option is incorrect as their policies were not to encourage Jewish emigration from other places (in fact, later they had policies to force emigration from Germany and then extermination). The third option is wrong because they eventually wanted to remove Jews from Germany (through emigration and then the Holocaust), not prevent them from leaving. The fourth option is incorrect as the Nazis were anti - Jewish and did not want Jewish support. So the correct reason is that they blamed Jewish people for the country's problems.

Answer:

B. blamed Jewish people for the many problems in the country.
