Which states would probably oppose such a system?

I think you forgot to add some details but based on my research, the correct answers are Rhode Island, Delaware, and Georgia. These states would probably oppose a system wherein the number of votes each state had in the nation's legislature will be based on the state's population. These states will oppose because they are less populous. Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
