1. The correct answer for the first question would be the Weimar Republic.
After the World War I, Germany was in terrible condition. It was ravaged by war and forced to pay reparations for to other nations it was at war. In economic sense, it was a mess. The Weimar Republic was established and they had to fight hyperinflation and other economic troubles and were not successful at doing so. The people did not have faith in this government.
2. The correct answer here is the Nazi Socialist Party.
As mentioned before the Weimar Republic was inefficient and did not solve numerous economic problems the Germans were facing in the period between the two wars. The charismatic Adolf Hitler, the leader of the Nazi Socialist Party managed to use the situation and rise to power by blaming the Republic for accepting such unfavorable peace treaty and become the Chancellor.
