Answer:
1) A
2) C
3) B
Step-by-step explanation:
1) A because the compromise conceded Missouri as a slave state but would not allow any state above the 36 30 line to become a slave state
2) C because nullification is the legal theory that if the state deems federal law unconstitutional it can nullify the law. However, it is not actually a "law."
3) B because the Dred Scott ruling stated that the U.S. consitution would not consider slave (African Americans) as individuals with rights. Rather they were still property and could not hold the same rights as a white man.
