Final answer:
The Constitution provided a stronger federal authority and a balanced governmental structure, including the ability to tax, regulate commerce, and a system of checks and balances, as opposed to the weak central government and inefficiencies of the Articles of Confederation.
Step-by-step explanation:
The Constitution is considered superior to the Articles of Confederation for several key reasons, two of which include stronger federal authority and the creation of a balanced governmental structure. Under the Articles of Confederation, the federal government lacked the power to tax and regulate commerce, which significantly weakened its ability to operate effectively. In contrast, the Constitution established a federal system that could levy taxes, regulate interstate commerce, and provide for national defense. It also set up a bicameral legislature and a robust executive and judiciary, thereby establishing checks and balances among the branches of government.
The new framework provided by the Constitution aimed for a “more perfect union,” as stated in its preamble, primarily by addressing the inefficiencies and lack of centralized power that plagued the Articles of Confederation. Consequently, the Constitution laid the foundation for a stronger national identity and enhanced capacity to act as a unified nation.
