The problems with the Articles of Confederation that prompted the framers to seek a stronger federal government, as outlined in the Constitution, include:
-
How to resolve disputes between states over land - The Articles of Confederation did not provide a strong federal mechanism to resolve conflicts between states, particularly over land claims.
-
Confusion over different state currency - Under the Articles, states could issue their own currency, leading to confusion and difficulties in trade and commerce due to lack of a unified monetary system.
The other two options (different ideas on how to make a federal education system and how to set up reserve land for Native Americans) were not primary issues that led to the call for a stronger federal government in the context of the Articles of Confederation.
