The source of the Supreme Court's authority is

Moral suasion
Judicial activism
Concurring opinion
Dissent

My answer: judicial activism

Nope.

Judicial activism is interpreting the Constitution in light of modern customs. Some Americans object to this.

It's either C or D, but beyond that I can't help you. Ms. Sue is gonna hate me for narrowing it down :/

Actually, the correct answer is not "judicial activism." The source of the Supreme Court's authority is not any of the options given in your question. The main source of the Supreme Court's authority can be traced back to the United States Constitution.

The Constitution, specifically Article III, establishes the Supreme Court as the highest judicial body in the country. It grants the Court the authority to interpret the law and make final decisions on significant legal issues. This authority is reinforced by the principle of judicial review, which allows the Court to determine the constitutionality of laws and actions taken by the government.

Furthermore, the Court's authority is based on the concept of the separation of powers, which ensures a balance of power among the three branches of the U.S. government. The Supreme Court's role is to exercise judicial power independently and impartially, while the other branches (the executive and legislative) have their own distinct powers.

So, to summarize, the source of the Supreme Court's authority is primarily derived from the United States Constitution, including the provisions granting judicial power and the principle of judicial review. It is not derived from moral suasion, concurring opinions, or dissent.
