Answer 1

The Treaty of Versailles was not ratified by the U.S. Senate due to concerns over reduced congressional war powers and foreign control of the League of Nations, which led to a period of American isolationism.

Step-by-step explanation:

The event that was an effect of World War I is a) The U.S. Senate refused to ratify the Treaty of Versailles. This historic decision was influenced by multiple concerns, including Senate fears that joining the League of Nations would entangle the U.S. in international disputes and diminish their power to declare war. Additionally, there was apprehension over Britain and France's potential control over the League.

The U.S. Senate's dismissal of the treaty had significant repercussions for international politics, weakening the League's effectiveness in resolving conflicts and marking a period of isolationism in American foreign policy.
