The correct answer is: it solved the dispute between big states and small states.

The Great Compromise, also known as the Connecticut Compromise, was necessary at the Constitutional Convention because there was a disagreement between the large states and small states over how representation in Congress should be determined. The large states favored a system based on population where they would have more representatives, while the small states wanted equal representation for all states. The compromise reached was a bicameral legislature, with the House of Representatives based on population (favoring the large states) and the Senate having equal representation for each state (favoring the small states). This compromise satisfied both factions and played a crucial role in the development of the United States Constitution.
