requires more natural capital relative to any point along Q1 or Q2.
B) Any point along Q2 represents a combination of resource outputs that
requires more human-made capital relative to any point along Q0 or Q1.
C) Any point along Q0 represents a combination of resource outputs that
requires more human-made capital relative to any point along Q1 or Q2.
D) Both a and b
E) None of the above
