Final answer:
Most Founding Fathers agreed that the issues with the Articles of Confederation pointed to a need for a stronger national constitution to address the limitations of the federal government regarding taxation, raising an army, and adapting to change.
Step-by-step explanation:
The problems encountered in the new United States under the Articles of Confederation led most Founding Fathers to agree that the federal government needed a stronger national constitution. This understanding stemmed from several issues, including the national government's lack of power to tax, pay down the national debt, raise an army, and handle economic downturns effectively.
The Articles made it almost impossible to enact necessary changes due to the requirement of unanimous consent from all states. The inadequacies of the Articles, highlighted by events such as Shays's Rebellion and ongoing economic struggles, convinced many that a robust, central authority was essential.
