Question

one way hitler violated the treaty of versailles in the 1930s was by○ disarming the military.○ rearming the military.○ encouraging nationalism.○ promoting isolationism.

Explanation:

The Treaty of Versailles strictly limited Germany's military size and banned conscription/rearmament. Hitler openly rebuilt Germany's military in the 1930s, directly violating this term. Encouraging nationalism was not a specific treaty violation, disarming was the opposite of his actions, and isolationism was not a violation of the treaty's terms.

Answer:

rearming the military
