Final answer:
To answer the student's implied question, the Constitutional Convention indeed aimed to revise the Articles of Confederation. The Necessary and Proper Clause does not limit but extends the powers of the U.S Congress. The United Nations is a formal organization with various primary organs, excluding a World Congress.
Step-by-step explanation:
The student's question refers to the governing body of an international union, likely pertaining to the structure of international organizations such as the United Nations.
However, given the examples provided, it seems the question might be related to the Constitutional Convention's objective, which was to revise the Articles of Confederation, a fact that is true.
The Constitutional Convention, the power distribution of the United Nations, and the primary organs of such an international body are relevant topics in this context.
The Necessary and Proper Clause actually provides flexibility to the U.S. Congress in exercising its powers, contrary to limiting them, making this statement false. The United Nations is indeed a formal organization where states are members, making it a platform where international diplomacy and policy are exercised.
The primary organs of the United Nations include the Security Council, General Assembly, and Secretariat, and do not include the so-called World Congress, which is false in the context of the U.N's primary organs.
