Final answer:
The United States Government under the Articles of Confederation established a system for governing the Western territories and created an open market for interstate trade.
Step-by-step explanation:
The United States Government under the Articles of Confederation can be considered a success because it provided a system for governing the Western territories that aided the nation's expansion. This system established guidelines for the admission of new states into the Union, setting the stage for westward expansion. Additionally, the government created an open market that fostered interstate trade by prohibiting tariffs and trade barriers between states, promoting economic growth and cooperation. However, the Articles of Confederation did not establish a strong, widely respected foreign policy or set the nation on a solid financial base, which were significant challenges.
