Scenario #4: Ethan filled 10 cups of the same size with equal amounts of water. He divided the cups into five groups of two cups each. The groups were placed in five
different locations around his house. After two weeks, he measured the remaining water
to determine how much had evaporated, by measuring how much water remained in
each cup
