In what ways was the confederation congress ineffective

The correct answer to this open question is the following.

The Confederation Congress was ineffective because the resulted Articles of Confederation left a weak central government that did not have the power to collect taxes. The states maintained their sovereignty and they indeed were the ones that could raise money through taxation. If the central government needed money, it had to ask for it for the states. The central government only could operate post offices or deal with Native American Indian tribes' issues.

federal power is further limited with a system of checks and balances that gives each branch of government a measure of power over the others.
