Which of the following was an achievement of the U.S government under the Articles of

Confederation?
OIt forced the Spanish to allow U.S usage of the Port of New Orleans.
O Power was taken away from the states and given to the national government.
O The United States adopted the U.S Constitution.
C Under the new Constitution, slavery was abolished in all states.

The correct option of the given choices would be:

A) It forced the Spanish to allow U.S usage of the Port of New Orleans.

The Articles of Confederation was the first constitution of the United States, which was in effect from 1781 to 1789. During this period, the U.S. government had limited powers and faced several challenges. One of the significant achievements under the Articles of Confederation was the successful negotiation to gain use of the Port of New Orleans.

To arrive at this answer, you can eliminate the options that are incorrect:

B) Power was taken away from the states and given to the national government - This is not an achievement of the U.S government under the Articles of Confederation because the power was actually distributed among the states, and the national government had limited authority.

C) The United States adopted the U.S Constitution - This is not an achievement of the U.S government under the Articles of Confederation. The U.S Constitution replaced the Articles of Confederation and was adopted in 1787.

D) Under the new Constitution, slavery was abolished in all states - This is also not an achievement of the U.S government under the Articles of Confederation. The U.S Constitution did not abolish slavery, and it took several decades and the Civil War for slavery to be abolished in the United States.

By a process of elimination, the correct answer is A) It forced the Spanish to allow U.S usage of the Port of New Orleans.
