Which of the following is not true about the articles of confederation? a. all of the 13 states needed to approve this for it to become valid b. it took four years to get approved c. it established a strong central government d. it became valid before the revolutionary *** i'm getting sick and tired of waiting so whoever answers this gets 50 points***

it established a strong central government

Clarification: The Articles did not make the central government more strong.  In fact, it actually made it weaker. It gave all the power to the states (e.x. making laws), and not the central government.

explanation:

the addition to geographic boundaries that might have  kept the people of the huang river civilization from traveling to far distance region is that they had learned about the other river valley civilizations but feared contact would bring invasion.

hope this .
