Answer: B. domestic economy and security.
Shay's Rebellion was an armed uprising in Massachusetts during 1786 and 1787. Daniel Shays led 4,000 rebels in a protest against economic and civil rights injustices.
The federal government was unable to finance troops to put down the rebellion, so it was put down by the Massachusetts State militia and privately-funded local militia. This event highlighted problems of domestic economy and security, and it is considered a catalyst for the Constitutional Convention.
