Struggling to understand question sets.py

Hi I've been staring at this question for half an hour and don't know where to begin. Maybe a couple more examples of inputs to the function and outputs might help? I've been playing with sets in the Powershell to gain some confidence with the methods but I don't think I understand the questions wording and how to apply it. Regards Dan

sets.py 
COURSES = {
    "Python Basics": {"Python", "functions", "variables",
                      "booleans", "integers", "floats",
                      "arrays", "strings", "exceptions",
                      "conditions", "input", "loops"},
    "Java Basics": {"Java", "strings", "variables",
                    "input", "exceptions", "integers",
