Question

the treaty of versailles, which ended world war i, contained a clause that blamed the war on
the united states government.
the aryans.
the german government.
the nazi party.

Explanation:

The Treaty of Versailles included the War Guilt Clause (Article 231), which formally placed full responsibility for starting World War I on the German government and its allies. The other options are incorrect: the U.S. joined the war later and was not blamed; the Aryans were a racial concept promoted by the Nazis, not related to the treaty's blame; the Nazi Party did not exist during WWI (it was founded after the war).

Answer:

the German government.
