What does bicameralism mean in the U.S. Congress?

• A. A one-house legislature with only the House.
• B. A system where the executive and legislative branches share authority.
• C. A three-branch government separation of powers.
• D. A two-house legislature (Senate and House).

Answer: (D)

Bicameralism means a two‑house legislature. In the United States, Congress is split into the Senate and the House of Representatives. Bills must be approved by both chambers to become law, which creates checks and balances within the legislative process and brings in different perspectives: the Senate tends to represent states with equal, longer terms, while the House represents the people based on population. This structure originated from the Great Compromise to balance the interests of large and small states. The other descriptions don’t fit because they refer to a unicameral legislature, a mix of executive and legislative power, or a broader three-branch idea rather than the two‑chamber setup of Congress.
