Two groups of people, the Yellow Group and the Orange Group, suddenly find themselves in a world where there are only two 'production opportunities': pumping water and picking berries. After a little while the Yellow Group has learned that it seems to produce about 2 gallons per hour while pumping water and about 8 berries per hour while picking.

Meanwhile the Orange Group has learned that it seems to produce about 1 gallon per hour while pumping water and about 3 berries per hour while picking.

If there is a division of labor and trade between the Yellow Group and the Orange Group, then it would be possible for each group to consume than they could if each group consumed what it produced itself.

A. more berries (but not more water)

B. more water (but not more berries)

C. more water and more berries

D. none of the above
