Multiple Choice

In the diagram in Question #7 above,

A) a movement from point S to point T involves an increase in the capital/labor ratio used In the production of good A.
B) if the PPF is plotted from the "contract curve" (or "production efficiency locus") , the Production combination of goods A and B associated with point R is on the PPF.
C) if the PPF is plotted from the "contract curve" (or "production efficiency locus") , with Good A on the vertical axis and good B on the horizontal axis, the production Combination of goods A and B associated with the 0_B origin is at the origin of the PPF graph.
D) if the PPF is plotted from the "contract curve" (or "production efficiency locus") ,With good A on the vertical axis and good B on the horizontal axis, the production Combination of goods A and B associated with point T is further up the vertical Axis than the production combination associated with point S.
