Answer:
a two-house Congress
Step-by-step explanation:
The Great Compromise sometimes called the Connecticut compromise proposed by the committee headed by Roger Sherman during the 1787 Constitutional convention.
It called "a two-house Congress, " whereby each state will have several representatives in the federal House based on the size of the population and an equal number of representatives at the Senate level regardless of the population.
Hence, in this case, the number is "a two house."
