How were state constitutions important to the writing of the u. s. constitution? a. most states had learned that having a strong central government was a mistake. b. small and large states came to the constitutional convention agreeing on how to set up a congress. c. none of the state constitutions contained guarantees of personal rights and freedoms. d. lessons learned in setting up state governments were in setting up the united states government.

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.
