Final answer:
The Articles of Confederation granted powers to Congress and had strengths such as ending the Revolutionary War and admitting new states to the Union.
Step-by-step explanation:
The Articles of Confederation was the first constitution of the United States, which was in effect from 1781 to 1789. Under the Articles, Congress had several powers, including the authority to declare war, make peace treaties, establish and maintain an army, create a postal system, and manage Native American affairs. These powers allowed Congress to function as the central governing body of the new nation.
Two strengths of the new government under the Articles of Confederation were the ability to negotiate and sign the Treaty of Paris in 1783, which officially ended the Revolutionary War, and the establishment of the Northwest Ordinance in 1787, which provided a process for admitting new states to the Union.
