Which of the following describes the primary purpose of a brief?

The primary purpose of a brief is to summarize the case for the judge. A brief is a written document presented to the court that concisely outlines the facts of the case, the legal issues involved, and the arguments being made. It serves as a tool to aid the judge in understanding the pertinent information and legal precedents relevant to the case at hand. This enables the judge to make an informed decision based on the arguments and evidence presented by both parties.

The other options do not encapsulate the main purpose of a brief. Outlining potential penalties for the defendant is typically part of the sentencing stage of a case, not the purpose of a brief. Providing legal mentoring to clients is a function of legal counsel rather than documentation submitted to a court. Recording witness testimonies is part of trial procedures, where testimonies are given in court, rather than summarized in a legal brief. Thus, the correct answer highlights the brief's role as a summary that effectively communicates the essential aspects of the case to the judge.
