What are the two parts of the U.S. Congress?

The U.S. Congress is a bicameral legislature, meaning it consists of two separate chambers, which are the Senate and the House of Representatives. This structure is fundamental to the legislative process in the United States, ensuring that various viewpoints and interests are represented more effectively. The Senate is composed of two senators from each state, providing equal representation regardless of state population, while the House of Representatives is based on the population of each state, creating a system of representation that reflects the demographic diversity of the nation. Together, these two bodies work to create, amend, and pass legislation, serving as the cornerstone of the federal legislative process. The other options do not accurately describe the U.S. Congress, as they refer to different legislative bodies or branches of government that do not apply in this context.
