Cоnsider the grаph аbоve where the hоrizontаl and vertical axes represent the number of points obtained by a seller and a buyer in a particular class exercise. Imagine that the shape in the graph above represents the Bargaining Zone. Every point on the edges of or within the shape above are possible outcomes from a given negotiation exercise. Each line segment & end point is labeled with a letter. Black letters are used to label line segments (not including their end points) and blue letters are used to label end points. Using the letter labels, indicate ALL the line segments and end points that can be considered Pareto Optimal. (Note: You will lose points for selecting letters that are not Pareto Optimal.)
