Which term describes a legislature with two houses?

• A. Republic
• B. Unicameralism
• C. Bicameralism
• D. Federation

Answer: (C)

Two-chamber legislatures are described by the term bicameralism. This term literally means two chambers, indicating a legislative body made up of two separate houses that both participate in lawmaking. The two houses often have different methods of representation and powers, providing internal checks and balances and allowing for diverse perspectives before a law passes. For example, one chamber might represent states equally, while the other bases representation on population, offering both regional and popular input.

Unicameralism describes a legislature with only one house, so it doesn’t fit two-chamber structures. A republic is a form of government where representatives vote for the people, not a description of how many legislative chambers there are. A federation is a political system with a central government plus constituent political units, which again concerns power sharing rather than the number of legislative chambers.
