Answer: B) Congress could not raise an army
Explanation:
Shays’s rebellion showed that Congress limited powers under the Articles of Confederation and especially the lack of authority to fund an army that could have suppressed the revolt were weaknesses that could lead to the collapse of the new government. The Constitution signed in 1787 was a result of the debate over the authority of the US government, and Shays’s Rebellion was the example needed for that Constitution to grant powers to the states to suppress revolts.
