What plan, favored by large states, proposed representation based on population and was unicameral?

The Virginia Plan was significant because it advocated for a system of representation in Congress that was based on the population of individual states. This was particularly appealing to larger states, as it meant they would have more representatives and thus more influence in the legislative process. The proposal called for a bicameral legislature, which ultimately led to a debate that shaped the structure of the U.S. Congress.

While many other plans were proposed during the Constitutional Convention, the Virginia Plan stood out for its emphasis on population as the basis for representation. This approach helped to address the concerns of larger states that felt they would be underrepresented under other proposals, such as the New Jersey Plan, which favored equal representation regardless of state size. The discussions stemming from the Virginia Plan ultimately contributed to the Great Compromise, which balanced the needs of both large and small states in the newly formed government.
