Question

arms reduction and settling border disputes contributed to the league of nations goal of
o punishing germany for world war i.
o making europe more powerful.
o solving international social problems.
o preventing future warfare.

Explanation:

The League of Nations was established after World War I with the aim of maintaining peace. Arms reduction reduces the means for war, and settling border disputes removes a common cause of conflict. These actions are clearly related to preventing future warfare. Punishing Germany was more of a focus of the Treaty of Versailles. Making Europe more powerful was not the main goal. Solving international social problems is a broader category but not as directly related as preventing warfare.

Answer:

preventing future warfare.
