Great job! Article 3 of the United States Constitution deals with the judicial branch. To arrive at this answer, one would typically refer to the Constitution itself or a trusted source that outlines the different articles and their respective subjects. In this case, one could read or search for the specific contents of Article 3, which would reveal that it discusses the establishment, powers, and functions of the judicial branch.
