Which of the following is true about supreme court justices? a. they are the country’s foremost authorities on state constitutions. b. justices throw cases away if, after reviewing them, they cannot reach a majority. c. they are the country’s foremost authorities on the constitution. d. there are eight permanent members of the court and one temporary chief justice.

The correct answer is:

Answer A is incorrect.  Each state has its own Supreme Court for that purpose.

Answer B is incorrect.  In some cases, where there has been an even number of justices on the court, review of a case may end in a split decision.  When a split decision occurs, then the Supreme Court's action (or lack of action, we could say) doesn't establish any legal precedent in the matter.

Answer D is incorrect.  The Chief Justice and Associate Justices all serve for life or until resignation.   There are no "temporary" justices.
