Which one of the following was a problem caused by the article of confederation

Congress couldn't levy taxes.

Explanation:

The Congress had the power to declare war and enter into treaties with foreign powers. It could establish a postal service and coin money. However, the Congress couldn't levy taxes.

The Articles of Confederation fell short in multiple ways. The problem was the articles did not allow the federal government sufficient power to sustain the union efficiently. They did not have the power to levy taxes, coin an official currency, or regulate trade. These issues weakened the national economy. States had much more power to the extent they could impose their own laws and ignore laws passed by the legislature let alone enforce laws.
