You know, come to think of it, there was a lot of information about the sun out there. Torii thought about the things she knew. You could get a sun tan by laying out in the sun, but she doubted seriously the professor was looking for any information on sun tanning. Although, the Head Boy himself had just suggested that very thing, so she'd been beaten to the punch.

Oh, well.

As another thought came to mind, Torii raised her hand. "The sun helps us measure time. For example, when the earth makes one full revolution around the sun, we know that a year has passed," she said. There was also the measuring a day, too, but she decided to save that idea for somebody else to suggest.
