Why was it difficult to run coalition governments in the Weimar Republic?

Correct answer: Many parties had different interests and ideas

The direct answer is A: coalition governments were difficult because many parties had different interests and ideas. Proportional representation allowed several parties to win seats. Since no single party always had a clear majority, parties had to join together to form a government. Such a coalition needed agreement on policies, budgets, and leadership. Disagreements could cause a coalition to collapse. Option A is correct because it identifies the real problem of differing interests. Option B is wrong because the parties were not all the same; their differences were important. Option C is wrong because elections did take place in the Weimar Republic. Option D is wrong because Germany did have a President. The key chain is many parties, no clear majority, difficult negotiations, and unstable coalitions. Memory cue: coalition means cooperation among different parties, so disagreement can produce instability.
