Hi Sri,

Without the answer choices to choose from, my interpretation will be based on the layout of the table (and a bit of logical inference). Since the table is built around the SUN, I would assume that the Sun appears on the Vertical access (Luminosity) at the "1" level. By extension, if it's at the "middle" of the Luminosity Scale, then it's probably at the "middle" of the Temperature Scale. Thus the Sun would probably be considered a "main sequence" star.

For the second question, "the group with the greatest RANGE of temperatures, aside from the main sequence stars" is the "white dwarfs" (since it's range is about 15,000K to a little less than 40,000K).

GMAT assassins aren't born, they're made,
Rich
