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

The U.S. Congress is comprised of two distinct chambers: the Senate and the House of Representatives. This bicameral structure was established by the U.S. Constitution, reflecting the aim to balance the representation of both populous and less populous states within the federal legislative framework.

The Senate consists of two senators from each state, regardless of the state's population, which ensures equal representation among all states. In contrast, the House of Representatives is based on the population of each state, allowing larger states to have a greater number of representatives, which reflects their larger populations in legislative discussions.

Together, these two chambers work collaboratively to draft and enact federal legislation, with each having its own unique powers and responsibilities, such as the Senate's role in confirming presidential appointments and the House's responsibility for initiating revenue bills. This division fosters debate and multifaceted representation in the legislative process.

The other choices refer to different legislative bodies from other countries or incorrect terms that do not represent the structure of the U.S. Congress.
