What is one primary role of the House of Representatives?

The primary role of the House of Representatives is to make laws. This function is foundational to the legislative process in the United States. Each member of the House is elected to represent their constituents, and through their collective efforts, they propose, debate, amend, and ultimately vote on legislation. The House serves as one half of the bicameral Congress, with the Senate being the other half, and all proposed laws must pass through both chambers before they can be sent to the President for approval.

In contrast, the other options describe roles that are not within the purview of the House of Representatives. For instance, electing the President is primarily the function of the Electoral College, with the House playing a role only in a unique situation such as a tie. Interpreting laws is the responsibility of the judicial branch, which includes the courts. Additionally, serving as the judiciary branch is not a role of the House; that responsibility lies with the judicial system, ensuring checks and balances within the government. Thus, making laws is the correct and defining role of the House of Representatives.
