Answer:
When a jury is needed for a trial, the group of qualified jurors is taken to the courtroom where the trial will take place. The judge and the attorneys then ask the potential jurors questions to determine their suitability to serve on the jury, a process called voir dire.
Jury trials educate jurors about the justice system. People who serve on juries have a greater respect for the system when they leave.
Article III, Section II of the Constitution establishes the jurisdiction (legal ability to hear a case) of the Supreme Court. The Court has original jurisdiction (a case is tried before the Court) over certain cases, e.g., suits between two or more states and/or cases involving ambassadors and other public ministers.
