Explanation:

Shays's Rebellion was a protest of the ex-revolutionaries who became farmers against the economic policies of the state in 1786, by the farmers of Western Massachusetts led by Daniel Shays's. By 1787, it became a full military confrontation. Ex-revolutionaries took the farming job but the taxes on them were higher than in the British period and the inability to pay taxes resulted in the foreclosure of property. At the time of this rebellion, the United States was governed by Article of Confederation and the rebellion exposed the weakness of the Congress to deal with the situation.

both are true, the congress does have the power to create banks, even if this power is not specifically described in the constitution, since there is nothing restricting it and there is power given to the congress to make "all laws which shall be necessary and proper". maryland was not allowed to tax a branch of the national bank operating there, and the supreme court decided that no state could. both of these topics were discussed in a decision of the mcculloch v. maryland case in 1819.
