Which of the following is NOT one of the four purposes of the United Nations?

The correct answer identifies an idea that is not one of the established purposes of the United Nations. The United Nations was founded in 1945 with several key objectives aimed at promoting peace and cooperation among nations. These include maintaining international peace and security, fostering friendly relations among countries, promoting social progress, better living standards, and human rights, as well as providing a platform for dialogue to address global issues.

While it seeks to encourage collaboration among nations, the establishment of a one-world government is not one of its aims. This concept implies the centralization of power across all nations under a single governing body, which goes against the UN's objective of respecting national sovereignty. The focus on peacekeeping, addressing global challenges such as hunger and disease, and fostering friendly international relations reflects core missions of the organization, whereas the concept of forming a one-world government does not align with these principles.
