Halakha
just believe in God and do the 7 rules that he gave to Mosses
For Jews, all Jews had to wear armbands on their clothes. Jews could not ride bikes or drive cars. Jews were not allowed in certain stores. Many people called Jews, "Dirty Jews". Jews did not have many rights at all. If they disobeyed the rules, almost all of the time you will have a death penalty if you were at a concentration camp.
Yes, they do.

During the actual Holocaust Jews were not supposed to go to school at all.
yes for ordodox and ultra-orthodox jews reform jews might adapt the rules of shabbat
None-it was the other way around.
moses presented rules of health to the jews around 1205bc
They limited them and put rules on them, and later moved them to ghettos.
The main teaching is the entire Torah and its laws.
Orthodox Jews are the people that want to keep tradition. Reform want 2 change things. I think that Orthodox Jews chose to break away from orthodox tradition and become reform Jews because they didn't like the whole tradition of orthodox Jews and all the rules they had to stick to such as observe all 613 laws as strictly as possible. So I think they changed so that they could have a bit more freedom from all these rules although there were still rules being reform Jews but at least if they change to reform Jews it changes (reform means change things).
