Answer: B. only <em>three-fifths</em> of the enslaved population would be counted when calculating each state's representation in Congress.
The Three-Fifths Compromise was reached during the 1787 United States Constitutional Convention. The question was whether the slave population would count when determining a state total's population number, which would be used to determine the number of seats that each state would have in the House of Representatives.
The compromise that was reached was to count every three out of five slaves as a person for this purpose. It gave the Southern states a third more seats in Congress than if slaves had been ignored.
Well one push factor would be they wanted to escape religious and political prosecution. Another is the Potato Famine. This was when their potatoes were contaminated and many died from starvation and disease.
I hope this helps somehow ;)
