Answer:
Lack of authority to impose uniform commercial regulation among the states.
Step-by-step explanation:
One of the problems of the Articles of Confederation was the fact that each state was largely independent from others when it came to commercial regulation. Because of this, each state was able to regulate trade in any way it saw fit. This made it difficult for other countries to conduct trade with the United States. The Annapolis Convention was held in order to develop a consensus when it came to the trade barriers that each state implemented.
