Final answer:
Neither the Virginia Plan nor the New Jersey Plan was fully adopted; instead, the Constitutional Convention reached the Connecticut Compromise, combining elements of both plans to create a bicameral Congress with a balance of proportional and equal representation.
Step-by-step explanation:
At the Constitutional Convention of 1787, delegates recognized that the Articles of Confederation lacked a strong centralized government. James Madison of Virginia proposed the Virginia Plan, advocating for a strong national government with a bicameral legislature based on state population, which favored larger states. In response, William Paterson presented the New Jersey Plan, supporting a unicameral legislature where all states had equal representation, more suitable for smaller states. Neither plan was fully adopted; instead, a compromise known as the Connecticut Compromise or the Great Compromise was reached. This blended the Virginia Plan's proposal for proportional representation in the lower house with the New Jersey Plan's equal representation in the upper house, resulting in our current Congress structure with a House of Representatives and a Senate.
