Question

the articles of confederation gave the national government the power to
impose taxes
issue money
enforce state borders
control state governments.

Explanation:

Under the Articles of Confederation, the national government had very limited powers. It could not impose taxes (that was a power of the states), it could not enforce state borders effectively (lack of a strong military - like force for that), and it could not control state governments (as the states retained a great deal of sovereignty). However, it was allowed to issue money.

Answer:

issue money
