[RM.03H]One location in the United States is facing unemployment problems. A student designs an activity to find out whether mining of minerals in the location would be economically feasible. The student calculates the costs and earnings listed below. A: Cost of land for mining
B: Cost of equipment
C: Cost of labor
D: Miscellaneous costs related to mining
E: Cost of reclamation
F: Earnings from selling the resulting mineral

Which of these is a correct conclusion about the solution to the problem of unemployment in the location?

Mining is a feasible solution to the problem if D is more than F – (A + B + C + E).
Mining is a feasible solution to the problem if F is less than (A + B + C + D + E).
Mining is not a feasible solution to the problem if E is more than F – (A + B + C + D).
Mining is not a feasible solution to the problem if C is less than (A + B + D + E + F).
