Question

as the weimar republic got weaker, the german people lost faith in
their economy.
us support.
socialist rule.
democratic rule.

Explanation:

The Weimar Republic was Germany's democratic government after WWI. As it weakened (due to economic crises, political instability, etc.), Germans lost faith in democratic rule, leading to support for authoritarian alternatives like the Nazis. The other options: the economy was a result of the Republic's weakness (not the main faith loss target here), US support wasn't the core faith focus, and the Weimar wasn't socialist (so "socialist rule" is incorrect).

Answer:

D. democratic rule.
