The correct answer is D) to what extent should the Supreme Court work to promote social progress.
Supreme Court justices who support judicial activism and those who support judicial restraint most disagree on the answer to this question: to what extent should the Supreme Court work to promote social progress?”
The Supreme Court of the United States was created to impart justice. Its roles are not to promote social progress. To do that, there are other branches such as the legislative branch or even the Executive Branch. So that is the point of view of those who support judicial restraint and the reason there are differences with those who support judicial activism.
The other options or the question were, a) what is the value of concurring of opinions that agree with a majority opinion?, b) how should new justices be selected for the Supreme Court in the event of a vacancy?, and c) should the Supre Court rule in cases that have already been heard by a lower court?
