Final answer:
Under the Articles of Confederation, Congress had the power to handle foreign affairs and set up post offices, while the authority to appoint members to Congress and deal with military leadership also fell under the jurisdiction of Congress, though not explicitly stated in the Articles of Confederation.
Step-by-step explanation:
Under the Articles of Confederation, the powers of Congress and the states were distinctly divided:
a) Foreign affairs - This was a power of the national Confederation Congress, which had the authority to exchange ambassadors, make treaties with foreign governments and Indian tribes, declare war, and handle related international matters.
b) Set up post offices - The power to set up post offices was actually a power given to the national government under the Articles of Confederation, allowing for the establishment of a system for mail delivery.
c) The members of the Confederation Congress - Each state legislature appointed delegates to Congress, with the authority residing in the hands of state governments to recall these delegates at any time.
d) Appoint military commander-in-chief - There was no separate executive branch or chief executive under the Articles of Confederation, so this power was not explicitly given to either Congress or the states. However, Congress had the power to direct military affairs.
The Articles of Confederation gave more authority to the states and limited the powers of the national government. The national government could not tax directly or regulate trade, and there was no national judiciary or executive leadership.
