Question from Princeton Review Adaptive test 4

IMO:C

IMO C

P1. The goal of mining companies is to discover the richest, most accessible sources of the ore they mine.

P2.Their success in reaching this goal, however, is not the sole factor determining the financial success of failure of a particular company.

Conc: Profits for mining companies are largely dependent on prices determined by the global supply of a given ore, not the amount of the ore supplied by any one company.

Which of the following inferences about mining companies is best supported by the information above?

(A) Discovery of a new source of ore could result in a financial loss for some mining companies.

(B) Mining companies should not invest in locating new sources of ore.

(C) Mining companies are consistently profitable as long as global supplies remain stable.

(D) Mining companies need to offset fluctuations in global supply by discovering new sources of ore.

(E) Mining companies cannot be profitable if the global supply of ore they mine increases.

IMO b/w D and E. However, I will go with D, because if global supplies fluctuate then they need to make up with more ore supplies since it is not a sole factor determining profit but is still one of the factors.

Very close b/w D and E, please post OA

The OA is A and I cannot for the life of me figure out why. This question really messed with my head.

A

Companies want to find new source to make enough revenue to offset its early expenses, but they don't want to find too many sources that the price of the ore fall sharply and then they lose money.

In my opinion C is the most logical one.
