The authors of the United States Constitution established a bicameral legislature primarily because they 1) wished states to retain their absolute sovereignty
2) reached a compromise between the large states and the small states over representation
3) hoped to weaken the power of Congress
4) wanted to create an independent judiciary elected by the people

reached a compromise between the large states and the small states over representation

Explanation:

In Bicameral legislatures, the authors of the constituent proposed that the legislative branch should be divided into two houses:

- House of the Senate:  Each states have two people that they can put in this house.

- House of the representatives: The numbers of people that each state can put in this house is depended on the number of their population.

Because of this, Many small states (who do not have a lot of population) believed that this design will be very bad for them and rejected the idea. So, a compromise was proposed. The small states will agree to do this if the bigger states agree that they will count "Slaves" that exist in small states as 3/5 part of the population.
