Mineralogy
Hello fellow humans. I have recently traveled to the newly discovered planet of Zircondrion…[where] I collected quite a bit of rocks and minerals. I am in the process of analyzing them, but I need YOUR help because I brought back too many. Will you analyze them and determine if they are minerals similar to those here on Earth?

The new coach spent many years at Sodden University, a school notorious for its poor field conditions, and would like to ensure that this new professional team does not suffer from a bad playing surface.
