Hello! Hope you are doing well today!
The answer to your question is:
Here are 5 weaknesses! you can pick which one you would like to put on your paper...,
1. No taxing power. The confederation government could not require states to pay taxes.
2. Inflation. The continental dollars were not backed by gold or silver so their value was inflated.
3. Jealousy and Arguing among states
4. Tariff Wars(tax wars)
5. Foreign Affairs in Shambles.
(hope this helped btw :))
