Why is it incomplete to understand Weimar’s weakness only through the constitution?

Correct answer: Because war defeat, Versailles, economic crisis and social violence were also causes

Answer: D. A constitution is important, but it works within a particular historical and social environment. Weimar’s early weakness was shaped by Germany’s defeat in the First World War, resentment over Versailles, severe economic problems and conflict in the streets. These pressures reduced confidence in democratic leaders and made political compromise difficult. D is correct because it identifies several connected causes instead of treating constitutional rules as the whole explanation. A is wrong because the constitution did matter. B is wrong because Germany faced major crises. C is wrong because Weimar was not fully stable. Notice that D does not deny constitutional influence; it adds the wider causes needed for a complete explanation. Memory cue: institutions matter, but circumstances shape how institutions survive.
