How did the assassination of the austrian archduke and his wife in sarajevo lead to world war i?

it would be  

germany had to pay all damages related to the war.

and i think

germany had to take sole responsibility for the war.

i do not believe this was true indefiantly the native americans would have lsot aganist america one they didndt have the resources and allies that america had and 2   indians werent as advanced at the time as they were not 3 americans had the expreince because some of the soliders from other wars fought in that war and were attecked etc

what exactly is the question to this?

there was a king, priests, and peasants.
