Answer:
The correct answer is 1. Shays's Rebellion demonstrated the weakness of the Articles of Confederation, leading to the Constitutional Convention. Shays's Rebellion was an armed uprising in western Massachusetts from 1786 to 1787, led by Daniel Shays, a former captain in the Continental Army. The rebellion was fueled by economic grievances and a lack of government intervention to address them. Under the Articles of Confederation, the federal government lacked the power to raise an army or regulate commerce, making it difficult to address the rebellion. This highlighted the need for a stronger federal government, leading to the Constitutional Convention in 1787 and the drafting of the United States Constitution.
