Answer:
e. was established in a spirit of cooperation before the war's actual end.
Step-by-step explanation:
Unlike the League of Nations, which was created after World War I, the United Nations was established during World War II, specifically in 1945. The founding of the United Nations was driven by a spirit of cooperation among the nations involved in the war, aiming to prevent future conflicts and promote international peace and security. This cooperative approach was a significant departure from the League of Nations, which was formed after World War I but failed to prevent the outbreak of World War II.
