The purpose of the League of Nations was to create a peaceful platform for resolving disputes between nations. To determine the correct answer, we can eliminate the options that are not related to peaceful dispute resolution. Option 2, "to form alliances," does not directly address the peaceful resolution of conflicts, so it can be eliminated. Option 3, "to resolve the start of World War I," is incorrect because the League of Nations was established after World War I, so it couldn't have been formed to resolve the war. Option 4, "to blame Germany for starting the war," is not accurate as the purpose of the League was not to assign blame for the war. Therefore, the correct answer is option 1, "to solve disputes between nations peacefully."
The purpose of the League of Nations was to solve disputes between nations peacefully.
