Question

how did a high enslaved population in the southern states threaten the people of the northern states?
○ it meant the exported crops would primarily come from the south.
○ it made it much harder to put an end to slavery.
○ it pressured the free states to reconsider the issue of slavery.
○ it potentially gave the south more power in the government.

Explanation:

Under the Three-Fifths Compromise, enslaved people were counted as 3/5 of a person for congressional representation and electoral college votes. A large enslaved population in the South increased their number of congressional seats and electoral power, which gave the South more influence in the federal government. Northern states feared this would let the South pass laws that favored their pro-slavery, agrarian interests over the North's industrial, anti-slavery (or restrictionist) goals. The other options do not represent a direct threat to Northern people's political interests in the same way.

Answer:

It potentially gave the South more power in the government.
