Which of the following was NOT true about the 1820 missouri Compromise?
A. It allowed Maine to enter the Union as a free state and Missouri to enter as a slave state.
B. It barred slavery north of the 36*30' line in future states from the Louisiana Purchase territory.
C. It successfully kept the issue of slavery from becoming a national debate until just a few years before the Civil War.
D. It temporarily settled the issue of slavery but was eventually weakened and ultimately overturned.
Answer: C
Explanation: The Missouri Compromise of 1820 addressed the divisive issue of slavery effectively enough that it remained submerged for the next 30 years. It was not until after the nation acquired new territory from the Mexican-American War in 1848 that slavery again emerged as an incredibly divisive political issue.
