How did the virginia plan aim to improve the structure of the national government?

The VA Plan was: "an arrangement, unsuccessfully proposed at the Constitutional Convention, accommodating a lawmaking body of two houses with corresponding portrayal in each house and official and legal branches to be picked by the assembly." 
This would make an intense council, and one overwhelmed by crowded states. The states with lower populaces legitimately expected this would decrease their energy to control the laws and operation of the government. The arrangement was connected exclusively to the lower branch of Congress (the House) and the portrayal of slave states was settled by the 3/fifth Compromise.

Popular sovereignty or the authority of the people referenced in the permeable of the constitution . this principle states that government power comes from the consent of the citizens.
