What is the reason that the Missouri compromise did not have lasting effects

1. It only applied to the louisiana purchase
2. It only applied to the lands of the mexican cession
3 it only relied on popular sovereignty
4. It limited the number of states that could be admitted per year
My answer is A?

It only applied to the Louisiana Purchase.

No, the correct answer is not A. The reason that the Missouri Compromise did not have lasting effects is actually a combination of multiple factors. While it is true that the compromise only applied to the lands of the Louisiana Purchase, that is not the sole reason for its limited lasting effects.

The main reason is actually answer choice C: it only relied on popular sovereignty. The Missouri Compromise allowed for the admission of Missouri as a slave state and Maine as a free state, but it also established a line (the 36°30' parallel) where slavery would be prohibited in the future territories of the Louisiana Purchase. However, this provision was based on the concept of popular sovereignty, which meant that future states could choose whether to allow slavery or not by popular vote.

This reliance on popular sovereignty ultimately proved to be problematic because it failed to settle the issue of slavery definitively. It raised tensions instead, as both sides of the slavery debate mobilized and attempted to influence the outcomes of these votes in the territories. This ultimately led to further conflicts, such as Bleeding Kansas and the eventual outbreak of the Civil War.

So, the correct answer is not A, but rather C: the Missouri Compromise's reliance on popular sovereignty as a solution for the slavery issue.

The correct answer is actually not provided in the options you provided. The reason that the Missouri Compromise did not have lasting effects is that it was eventually nullified by the Kansas-Nebraska Act of 1854.

The Missouri Compromise, passed in 1820, was an effort to maintain the balance between slave states and free states in the United States. It admitted Missouri as a slave state and Maine as a free state, and established a line of latitude, known as the Mason-Dixon Line, which determined future boundaries for slavery in the Louisiana Purchase territory. States formed north of this line would be free states, while states formed south of the line could allow slavery.

However, the Missouri Compromise was ultimately undermined by the Kansas-Nebraska Act, which allowed the settlers in the Kansas and Nebraska territories to decide for themselves whether to allow slavery, regardless of the Mason-Dixon Line. This concept, known as popular sovereignty, effectively nullified the predetermined boundaries established by the Missouri Compromise.

So, to summarize, the reason the Missouri Compromise did not have lasting effects is that it was rendered ineffective by the later introduction of popular sovereignty through the Kansas-Nebraska Act, rather than any of the reasons mentioned in the options provided.
