Final answer:
The weaknesses of the Articles of Confederation, demonstrated by Shays' Rebellion, the ineffectiveness of Congressional law enforcement, and the difficulties in amending laws due to the requirement for unanimous consent, were key reasons for a new Constitution.
Step-by-step explanation:
The problems caused by the weaknesses of the first Constitution, the Articles of Confederation, which resulted in writing a new one, are numerous. However, the correct choices regarding the reasons that led to the development of the new Constitution are:
- a. During Shays' Rebellion, there was no military to stop the revolting farmers. This highlighted the national government's lack of a standing army or the power to raise one to address internal conflicts.
- c. Congress was creating laws, but those laws were not being enforced. Under the Articles of Confederation, Congress lacked the authority to compel states to adhere to its laws.
- d. All of the states had different needs and some laws needed to be amended, but Congress had a hard time making changes because all of the states had to agree. This unanimity requirement made it virtually impossible to address the disparate needs of each state or adapt to changing circumstances.
Choices b and e are not correct as Congress was not effectively receiving payments, and the United States were not unified under the Articles of Confederation.
