A. Congressional representation
Step-by-step explanation:
The issue that the Great Compromise addressed was the problem with representation in Congress and how it should be counted.
During this time, the issue of how representation in Congress was going to be counted was dividing small and big states. Big states wanted representation in Congress based on population, while smaller states just wanted equal representation. This made it hard for them to come to an agreement since they both wanted something different.
The Great Compromise was a solution, where it would be a bicameral legislature. The upper house would have equal representation, which the smaller states wanted, and the lower house would have representation based on population, which the bigger states wanted.
Later, the Three-Fifths Compromise came about. This solved the problem of whether or not slaves should be counted towards the population of a state. The Southern states wanted the slaves to be counted, but the Northern states thought it was not right to count them since the South treated them as property, not as people. The Three-Fifths Compromise made it so three-fifths of a slave population counted towards the population of a state, which made both the North and South happy.
