HR Diagram Quiz

I cannot think of ANY diagram in all of Astronomy that is as important as the HR Diagram. I want my students to have a good understanding of the diagram and what we learn from studying stars and their position on it. You will be referring to the HR Diagram below for all of your questions. Good luck.
