What would have happened in 1818 if missouri had joined the union as a slave state?
a no other territory would have been granted statehood.
b the balance of power in congress would have shifted.
c states in the north would have been forced to legalize slavery.
d there still would have been fewer slave states than free states.

Correct answer choice is :

In an attempt to maintain the stability of power in Congress between slave and free states, the Missouri Compromise was declared in 1820 indicating Missouri as a slave state and Maine as a free state. Controlled as a province of Massachusetts since 1647, the appearance of Maine as a free state was admitted to by Southern legislators in exchange for the entrance of Missouri as a slave state.
