The name for the democratic German government from 1919 to 1933  defines the Weimar Republic.

Explanation:

Before the advent of Nazi rule, Germany was governed by a democratic set up from 1919 to 1933 and it was named after a town called Weimer. This was the place where the new government of democratic Germany was formed by the national assembly and it has been named as the Weimar Republic.

An election system has been put in place to elect the representatives under the parliamentary democracy system. The societal and financial mismanagement has totally destabilized the Weimer Republic besides the First World War. This made the fall of the Weimer Republic and that is the beginning of the Nazi rule in the year 1933.

the completion of the erie canal spurred the first great westward movement of american settlers, gave access to the rich land and resources west of the appalachians and made new york the preeminent commercial city in the united states.

i believe the correct answer is option b. most eastern european nations joined nato.

though i could be wrong, option d. the eastern european nations were granted complete independence, would be another choice.

hope this ! : )
