The federal government was too weak to enforce laws, is the right answer.
Explanation:
The Articles of Confederation which served as the First Governing document of the United States was written during a time when Americans feared a strong national government. They believed, a strong central government can re-establish a tyranny just as the British once had. Accordingly, the Articles of Confederation did not give some significant powers to the National Government such as to implement their laws and taxes.
