I got done with my hardest exam today :D

Feels like a relief, but I already know I missed one: What concept/term did Carl Sauer coin? I put Environmental Determination cause I honestly had no clue, but it was supposed to be Geographical Something. I thought I got it right, because this one girl said it was Least Cost Theory, but then I remembered that was by Weber, so it couldn't be! And then, a whole bunch of people put the same answer as me. Google and Barbara had abandoned me :/
