Step-by-step explanation:
The delegates to the Constitutional Convention in 1787 resolved their disagreement regarding slavery by creating a bicameral Congress through the Great Compromise, also known as the Connecticut Compromise. This compromise settled the dispute between large and small states by proposing a Congress with two houses. The upper house, the Senate, would have two members from each state, while the lower house, the House of Representatives, would have membership proportional to the population of each state.
