12. All of the following could immediately or eventually lead to an outward shift of a nation\'s production possibilities curve, EXCEPT:
A. immigration of skilled workers from other nations to our country.
B. an increase in the birth rate.
C. an increase in the average skill level of all occupational groups.
D. depletion/reduction of the availability of major energy resources.

Solution

The correct option is D
