(03.04 mc) question refers to the excerpt below. "if northerners found the three-fifths rule and slavery wrong, southerners were perfectly willing to drive home the logic of emancipation: emancipate them and they stay where they are; and two-fifths of their number will be added to the representation, though they are not permitted to enlist in our army."猶rofessor margo anderson, 2003 what concern of northerners did the southerners use in this argumen

The correct answer is: Representation in Congress.

Explanation:

The Southern states based their economy on slavery while the Northern states were free states, with bigger population due to the industrialization so their Representation in Congress was a big issue.

Debates of Missouri being admitted as a part of the Union after the Louisiana's Purchase generated two different opinions. That Missouri should be admitted as a free state because the Northern states were free states and were against slavery and that Missouri should be admitted as a slave state because every state should be able to make their own laws and decide if they wanted to have slaves or not.

Southern states supported Missouri's decision of being a slave state, so they argued that The Three-Fifths Compromise stated that 3 out of every 5 slaves were to be counted in order to establish representation in Congress, so if they were admitted as a slave state they would have less representation in Congress than they would have being a free state. Southern states also argued that African Americans in Northern states had different rights they couldn't join the army or enter to free public places, so it wouldn't make a big difference if Missouri was a free state or a slave state. Missouri was admitted as a slave state in exchange of Maine being admitted as a free state.
