Final answer:
Shay's Rebellion showed the United States that it needed a standing army.
The answer is option ⇒D
Step-by-step explanation:
During Shay's Rebellion, which took place from 1786 to 1787, a group of farmers in Massachusetts led by Daniel Shays rebelled against the state government. They were protesting against high taxes and debt, which were causing economic hardship for many farmers. The rebellion highlighted the weaknesses of the national government under the Articles of Confederation, which did not have the power to effectively respond to the uprising.
The lack of a standing army to suppress the rebellion exposed the vulnerability of the United States to internal threats. The national government had difficulty raising a military force to quell the rebellion, relying instead on local militias that were often ill-equipped and uncoordinated. This highlighted the need for a more centralized military force that could respond quickly and effectively to internal unrest.
As a result of Shay's Rebellion and other challenges faced by the young nation, such as the inability to collect taxes and regulate trade, there was growing support for the need to strengthen the federal government. This eventually led to the Constitutional Convention in 1787, where the United States Constitution was drafted to establish a stronger central government with the power to maintain a standing army and address internal conflicts.
The answer is option ⇒D.a standing army
