Compare the Pareto Efficient Allocations in the following cases in Edgeworth Boxes:

Person A does not care at all about her consumption of good 2 and person B does not care at about his consumption of good 1.

Consumer A has perfect complement preferences represented by the function U(x,y) = min(x,y) and consumer B has utility function U(x,y) = XY the aggregate endowment of good x is equal to the aggregate endowment of good y which is equal total x available = 20; total y available = 20.
