To arrive at this answer, we need to analyze the reasons behind changing the unicameral legislative branch created by the Articles of Confederation to a bicameral branch in the United States Constitution.

1. Research the purpose of a bicameral legislature: A bicameral legislature consists of two separate houses or chambers that share the legislative powers. This system is designed to ensure a system of checks and balances by separating the legislative power between the two chambers, which helps prevent the concentration of power in one single body.

2. Understand the weaknesses of the Articles of Confederation: The Articles of Confederation, the first constitution of the United States, created a unicameral legislative branch, known as the Continental Congress. However, this system proved to be inadequate in effectively governing the nation due to multiple weaknesses, such as the lack of a strong central government, difficulty in enforcing laws, and limited ability to raise revenue.

3. Consider historical context: The Articles of Confederation were in effect from 1781 to 1789, during which time the challenges and limitations of the unicameral system became evident to the Founding Fathers. They recognized the need for a stronger central government and a more efficient legislative branch that would address the issues faced under the Articles.

4. Analyze the purpose of the Constitution: The United States Constitution, ratified in 1788, aimed to address the weaknesses of the Articles and establish a more effective system of government. This included the creation of a bicameral legislative branch, with the House of Representatives and the Senate as the two chambers.

In conclusion, the reasons why the unicameral legislative branch of the Articles of Confederation was most likely changed to a bicameral branch in the United States Constitution was that people wanted more of a separation of government power. By having two separate chambers, each with its own set of powers and responsibilities, a system of checks and balances could be established to prevent the concentration of power and ensure a more balanced and effective government.
