Which of the following is a key function of Congress in relation to legislation?

The key function of Congress in relation to legislation is the proposal and passage of laws. Congress is the legislative branch of the federal government, comprising two chambers: the House of Representatives and the Senate. Its primary responsibility is to create, modify, and enact laws that govern the country. This process typically involves introducing a bill, debating its merits, and voting on it. If passed by both chambers, the bill is then sent to the President for approval or veto.

This legislative process ensures that diverse perspectives from both chambers can be considered, allowing for a comprehensive approach to lawmaking. The focus of Congress on proposing and passing laws is essential for addressing the needs and challenges faced by society and for implementing the priorities of the government. Other functions, such as judicial review, appointments, and enforcement, belong to different branches or levels of government and do not fall under the primary role of Congress.
