Final answer:
The subject of the most debate between large and small states at the Constitutional Convention was representation.
Step-by-step explanation:
The subject of the most debate between large and small states at the Constitutional Convention was representation. The large states, such as Virginia and Pennsylvania, wanted representation in the new government to be based on the population of each state. On the other hand, the small states, such as Delaware and Rhode Island, wanted equal representation for each state. This debate led to the creation of the Great Compromise, which established a bicameral legislature with representation based on population in the House of Representatives and equal representation in the Senate.
