Use the diagram to answer the question.
A graph illustrates the relationship between the luminosity (Sun = 1), ranging from 0.0001 to 10000, and temperature in Kelvin, ranging from 30000 to 3000, for various stars classifications. Main sequence stars extend diagonally from the top left to the bottom right corner of the graph. The White Dwarfs, Giants, and Super Giants are placed on the graph according to their luminosity and temperature.
