Final answer:
An oligarchy could fix the problems of the Articles of Confederation by establishing a stronger central government with more power.
Step-by-step explanation:
An oligarchy is a form of government in which a small group of individuals hold all the power. If an oligarchy were to fix the problems of the Articles of Confederation, they would likely establish a stronger central government with more power and authority. This would address the issues of the national government lacking the power to tax, pay down the national debt, raise an army, and maintain order. For example, the oligarchy could propose amendments to the Articles that grant the central government the power to tax and regulate trade, ensuring a stable economy and national defense.
