Question

The 1935 Nuremberg Laws isolated Jews in Germany by forbidding Jews from holding government jobs. prohibiting Jews from marrying non-Jewish Germans. forbidding Jewish doctors from treating non-Jews. prohibiting Jews from going to non-Jewish schools.

Answer 1

All of the above are correct.  They began isolating the Jews to keep the Aryan line pure.  They also burned books written by Jews and they were forced to work for low-paying jobs.  Later they were rounded up and brought to concentration camps where many were forced to work until they died.  Others were able to survive.

Answer 2

The statements you listed are all part of the 1935 Nuremberg Laws. These were designed to distinguish pure Germans from non-Germans (or jews in their heads). Due to the general worsening conditions against the jewish population, it was increasingly hard for them to actually achieve something prominent in their lifetime.
