Which of the following is a primary role of the Supreme Court in the U.S. government?

The primary role of the Supreme Court in the U.S. government is to interpret the U.S. Constitution. This function is crucial as it ensures that laws and governmental actions comply with constitutional provisions. The Court examines cases brought before it, determining whether they align with the rights and structures established in the Constitution. Through judicial review, the Supreme Court can uphold, strike down, or modify the interpretation of laws, thus playing a key role in shaping American legal and political landscapes. This process not only safeguards individual rights but also maintains the balance of power among the branches of government.

Creating federal laws falls under the purview of Congress, while enforcing federal laws is primarily the responsibility of the executive branch. Amending the Constitution involves a different process that requires significant consensus among state and federal legislators, which is not a task performed by the Court itself. Therefore, the interpretation of the Constitution remains the definitive function of the Supreme Court.
