Final answer:
The major function of the General Assembly within the United Nations is to engage in legislation processes, including research, drafting, and passing of resolutions about global issues.
Step-by-step explanation:
The major function of the General Assembly is the legislation process, which involves researching, writing, and passing resolutions that reflect the collective interests and concerns of international society. The General Assembly operates within the United Nations, where each of the 193 member states has an equal voice in discussions of global challenges such as the COVID-19 pandemic, climate change, and armed conflict. While these resolutions are a key aspect of international cooperation and policy-making, the General Assembly often does not have the power to enforce them, acting as a venue for the expression of global aspirations rather than a body with coercive power.
Nevertheless, the GA plays a pivotal role in shaping international norms and laws, especially in domains like space law, where its resolutions are widely acknowledged. In some cases, the Security Council might utilize General Assembly resolutions to justify sanctions or other measures against states.
