How did congress try to change the buying and selling of slaves? a. by forbidding the sale of slaves in the united states b. by passing a law assisting slaves in gaining their freedom in the north c. by forbidding the sale of slaves to foreign places d. by heavily taxing the importation of slaves into the united states (a and d are wrong but i’m not sure what the answer is )

The correct answer is option b. "by passing a law assisting slaves in gaining their freedom in the north". The Congress was trying to regulate the buying and selling of slaves, when the Missouri Compromise was stated in 1820. This bill prohibited slavery north of the southern boundary of Missouri, which assisted slaves to pursue their fight for freedom.

during both period congress passed law restricting the civil liberties of american citizen that meet with the overall public support is the one statement that explain the rate scare of the 1920 and 1950 is very similar
