What type of legislative structure does the U.S. government have?

The U.S. government operates under a bicameral legislative structure, which means it has two separate chambers in its legislative branch: the Senate and the House of Representatives. This structure allows for a system of checks and balances within the legislative process. Each chamber has distinct powers and responsibilities, which helps ensure a more thorough deliberation of proposed laws and provides opportunities for different perspectives to be considered.

The Senate, comprising two senators from each state regardless of population, serves to represent the interests of the states equally. In contrast, the House of Representatives is based on population, allowing for representation that reflects the demographic distribution of the country. This dual structure fosters a more comprehensive approach to lawmaking, as proposed legislation must be approved by both chambers before becoming law.

The other options represent different types of governmental frameworks. A unicameral legislature has only one chamber, which is not the case in the U.S. The federal structure indicates a division of power between national and state governments but does not specify the nature of the legislature. Lastly, a confederate system is one where smaller political units maintain most of the power, which does not accurately describe the U.S. government's centralized legislative process.
