Final answer:
A significant difference between the Articles of Confederation and the U.S. Constitution is the level of central authority and power.
Step-by-step explanation:
A significant difference between the national governments outlined in the Articles of Confederation and the U.S. Constitution is the level of central authority and power. Under the Articles of Confederation, the national government had limited powers and could not enforce its laws or collect taxes. This resulted in a weak central government that was unable to effectively govern the nation. On the other hand, the U.S. Constitution established a stronger central government with the power to enforce laws, raise taxes, and regulate commerce. This change in the balance of power was aimed at addressing the challenges faced under the Articles of Confederation and creating a more stable and functional government.
