Which one of these is NOT a strength of the Articles of Confederation? A.) Congress could sign treaties

C.) Established the postal service

D.) Had a strong central government

your answer would be a congress could not sign treaties. It's in your explanation says Congress had no power to Levy taxes or regulate trade without federal court system executive leaders that one was not a strength of the Articles of the Confederation

Explanation:

There were more weaknesses than strengths under the Articles of Confederation. The lack of power given to the Continental Congress strangled the federal government. The Articles gave Congress the power to pass laws but no power to enforce those laws. If a state did not support a federal law, that state could simply ignore it. Congress had no power to levy taxes or regulate trade. Without a federal court system or executive leader, there would be no way to enforce these laws, either. Amending the Articles of Confederation would also require a unanimous decision, which would be extremely difficult.
