Question

the articles of confederation were...
the first government of the u.s.
the first constitution
george washington’s plan for taking power as the new king
the king’s plan for how to govern the newly freed colonies

Explanation:

The Articles of Confederation served as the foundational governing document that established the first formal government of the United States after gaining independence, preceding the U.S. Constitution. The other options are incorrect: it was not the first Constitution (that is the U.S. Constitution ratified later), it had no connection to George Washington seeking power as king, and it was not a royal plan over freed colonies.

Answer:

the first government of the U.S.
