Lunch in Jamie's dorm is an all-you-can-eat buffet, served from 11 a. m. until 1 p. m. By noon, the buffet is picked over, and by 12:30, there are very few popular items left. The garbage bins, though, are full of food. Over time, you would expect that students would:

A. stop eating so much at lunch because they would notice that it generates waste.
B. start distributing themselves more evenly over the lunch hours to avoid long lines.
C. come earlier and earlier for lunch in order to have a better selection from which to choose.
D. be pickier in their selections from the buffet.
