What is a primary function of the Legislative branch?

The primary function of the Legislative branch is to pass laws. This branch is responsible for the creation and enactment of legislation, which governs the behavior of individuals and institutions within the state. In a democratic system, legislators are elected representatives who debate, amend, and vote on proposed laws, reflecting the will of their constituents.

While the other options describe important functions within government, they do not pertain to the core role of the Legislative branch. Executing national defense relates to the Executive branch, which oversees military and foreign affairs. Interpreting state disputes falls under the Judiciary, which is responsible for resolving legal conflicts and interpreting laws. Reviewing international treaties is also an Executive function, as it involves negotiating and managing relationships with other countries. Thus, the correct answer focuses specifically on the legislative process of lawmaking, which is foundational to governance and democratic representation.
