Answer:
The end of the Three-Fifths Compromise
Step-by-step explanation:
The Three-Fifths Compromise was the concept developed by James Wilson and Roger Sherman.
In this compromise, enslaved people were counted as three-fifths of a person. The benefit of counting enslaved people helped the Southern states to have more voting counts in the House of Representatives. This more seats would help them to have more power. But this would not be beneficial for the Northern States. So, they come up with the "Three-Fifths Compromise".
The Northern Congressman were wondering that the war would end this "three-fifths compromise".
So, the correct answer is the end of the Three-Fifths Compromise.
