What did opposition from both left and right mean for the Weimar Republic?

Correct answer: The republic had to face wide political instability

The direct answer is A: the republic faced wide political instability. Opposition from the left and the right means that important groups with very different political aims challenged the Weimar Republic. On the left, communist and revolutionary groups wanted a workers' revolution or a Soviet-style system. On the right, monarchists, conservative nationalists, and later Nazis opposed parliamentary democracy and wanted authoritarian rule or a return to strong national power. These challenges produced uprisings, political violence, attempted coups, changing governments, and difficulty in building stable support. Option A is correct because pressure from both extremes made the democratic government insecure and politically unstable. Option B is wrong because all parties were not happy; powerful groups openly rejected or attacked the republic. Option C is wrong because the conflict itself involved competing ideologies such as communism, conservatism, nationalism, and Nazism. Option D is wrong because Germany no longer had a ruling king after the monarchy ended; the issue was the struggle over what system should replace it. A useful cue is: left plus right opposition equals pressure from both sides and instability.
