Answer:
Allowing the citizens of each state to choose whether the state should prohibit slavery or not, could cause problems as it violated the country's sense of unity.
Explanation:
The problem of allowing citizens in each state to decide whether slavery should be banned or released in each state could cause many problems. This is because it infirms the sense of unity, causing the states to devalue each other and not see themselves as belonging to the same country. This would also weaken the federal government, which would not be able to establish a single legislation throughout the territory, which could create several political problems, as well as a strong regional prejudice.
