What is one responsibility of the legislative branch?

The legislative branch is primarily responsible for the creation and modification of laws, which includes previewing and amending bills. This process allows legislators to carefully consider proposed legislation, debate its merits, and make necessary changes before a bill is finalized and sent to the executive branch for approval. By thoroughly reviewing and refining bills, members of the legislative branch ensure that laws are well-crafted and address the needs of the public effectively.

The other functions presented in the choices align more closely with the roles of other branches of government; for instance, enforcing laws is the responsibility of the executive branch, while interpreting laws falls under the judicial branch's purview. The power to veto laws is also a function of the executive branch, primarily executed by the president or a governor, rather than the legislative branch itself. Therefore, the responsibility of previewing and amending bills is a fundamental duty specific to the legislative branch's role in law-making.
