Why was political polarisation a serious problem at the beginning of the Weimar Republic?

Correct answer: It made compromise and stable rule difficult

The direct answer is B: political polarisation made compromise and stable government difficult. Polarisation means that groups move toward strongly opposed positions and become unwilling to cooperate. In the early Weimar Republic, communists, conservatives, nationalists and other groups disagreed deeply about Germany’s future. When parties refuse compromise, coalition governments become fragile, decisions take longer and citizens may lose faith in democracy. B is correct because it explains the direct political consequence. A is wrong because polarisation does not unite parties. C is wrong because it did not make monarchy democratic. D is wrong because it did not end the Treaty of Versailles. Memory cue: “extreme sides mean fewer compromises and weaker governments.”
