Answer:
Connecticut Compromise.
Explanation:
The Connecticut Compromise took both the Virginia Plan and the New Jersey Plan, and merged them. It called for a two house (rather than a one house of both plans), and compromised both plans into one. In the Senate, the New Jersey plan was used, in which each state was only allowed 2 representatives each for basic equality, while in the House of Representatives, the Virginia Plan was used, to ensure that there was a proper ratio of representatives to the current population.
