What are the two chambers of the U.S. Congress called?

The two chambers of the U.S. Congress are correctly identified as the Senate and the House of Representatives. This structure is outlined in the United States Constitution, specifically in Article I, which establishes the legislative branch of the federal government. The Senate is composed of 100 senators, with each state represented by two senators, while the House of Representatives varies in size based on the population of each state, currently totaling 435 representatives.

Understanding this distinction is important not only for general knowledge of the U.S. government but also for the citizenship interview, as it reflects comprehension of the American political system and its checks and balances. The other options incorrectly name the components of Congress or use terminology that does not exist within the formal structure of the U.S. legislative system, such as the "House of Lords" or "House of Senate."
