Question

the missouri compromise dealt with what political controversy?
○ whether or not to pass tariffs to encourage american manufacturing
○ removal of the native americans from georgia
○ maintaining the balance between slave and free states in congress
○ developing a transcontinental railroad system

Explanation:

The Missouri Compromise was about keeping the balance of slave and free states in Congress. When Missouri wanted to enter as a slave state, it would upset the balance, so the compromise admitted Missouri as a slave state and Maine as a free state, and set a boundary for future slave states. The other options: tariffs relate to economic policies, Native American removal is the Trail of Tears, and transcontinental railroad is later. So the correct option is about maintaining the balance between slave and free states.

Answer:

maintaining the balance between slave and free states in Congress (the third option)
