Question

Which state made the proposal to create a bicameral national legislature, with representation based proportionally on each state's population?

Answer 1

George Madison of Virginia

Explanation:

The so called Virginia plan was based on the states's population. This plan would be modeled after the English parliament with a lower house for the common people with a short term of office and higher house for the more elite people with a longer term of office.
This plan favored the states with a higher population like Virginia , New York and Pennsylvania.
