Final answer:
The Virginia Plan called for a bicameral legislature with representation based on state population, giving an advantage to more populous states.
Step-by-step explanation:
Under the Virginia Plan, proposed by James Madison, the structure of the national government would have been transformed by creating a bicameral legislature in which the number of delegates per state would be based on the state's population. The lower house members would be elected by the people, and those members would then choose the upper house from a list of nominees provided by the state legislatures.
This plan favored states with larger populations, granting them more political power due to their proportional representation in both houses of the legislature. In contrast, the New Jersey Plan advocated for a unicameral legislature with equal representation from all states, regardless of size.
