Why was the relation between the old army and the new democratic government sensitive?

Correct answer: Because the new government had to depend on old military structures for order

Answer: C. The Weimar government was a new democratic authority, but it inherited older institutions and faced revolts and disorder. To maintain order, it had to rely on the existing army and other conservative forces. This created a sensitive relationship: the government needed their power, while those forces were not necessarily committed to democratic ideals. C is correct because it shows both dependence and political tension. A is wrong because the army did not disappear. B is wrong because the army did not write the Versailles Treaty; the victorious powers imposed it. D is wrong because dependence on an old power structure did not automatically make parliament fully independent. The key idea is continuity inside political change. Memory cue: new republic, old instruments of order.
