The correct answer is: "in the bicameral structure of the legislative power".
The Connecticut Compromise or Great Compromise was enacted in 1787 and it is an agreement that the different states reached during the Constitutional Convention, which would define the structure of the resulting federal legislative power.
Such legislative structure maintained the bicameral approach that had been previously proposed in the Virginia Plan, where the delegates from this state had expressed their support for the creation of a bicameral legislative branch.
