Exhibit 2-8 Production Possibilities Curve Data -As Shown in Exhibit 2-8, the Concept of Increasing Opportunity

Exhibit 2-8 Production possibilities curve data $$\begin{array} { | l | r | r | r | r | r | r | } \hline & \text { A } & \text { B } & \text { C } & \text { D } & \text { E } & \text { F } \\\hline \text { Capital goods } & 15 & 14 & 12 & 9 & 5 & 0 \\\text { Consume goods } & 0 & 2 & 4 & 6 & 8 & 10 \\\hline\end{array}$$

A) the quantity of consumer goods produced can never be zero.
B) the labor force in the economy is homogeneous.
C) greater amounts of capital goods must be sacrificed to produce an additional 2 units of consumer goods.
