Final answer:
The Articles of Confederation could have been improved by creating a stronger central government with the power to tax, regulate commerce, and amend more easily without unanimous state consent.
Step-by-step explanation:
After reviewing the successes and failures of the Articles of Confederation, changes that could have been made to create a more successful structure of government include establishing a stronger central authority. The government under the Articles had significant limitations, such as the lack of power to tax, raise an army, regulate commerce among the states, and enforce laws.
A major issue was the requirement for unanimous consent from all states to amend the Articles. This made it nearly impossible to adapt to new challenges. Additionally, the federal government was quite weak relative to the states, with most power resting in state governments.
To rectify these problems, a new system could have been designed to allow for a more flexible amendment process, giving the central government the ability to tax, regulate interstate commerce, and provide for national defense. The U.S. Constitution, which replaced the Articles, incorporated such changes, creating a balance between a strong central government and the independence of states.
