Environmental groups are aggressively protesting the proposed use of a new technique for mining oil from the fringes of underground aquifers. These groups complain that such mining will lead to instances of contaminated groundwater and to sinkholes and other disasters in areas near the proposed mining. But, as the mining companies are quick to retort, the countries already using this technique have not reported any groundwater contamination or environmental issues. Therefore, it is safe to proceed with the new technique.
Which of the following, if true, most undermines the conclusion above?
(A) Some of the countries currently using the new technique have only been doing so for two years or less.
(B) Other widely-used techniques used to procure oil have led to even worse contamination issues than what environmentalists predict could happen with the new technique
(C) The countries currently using the technique are so dependent on oil revenue that they are unlikely to report any problems that might require them to stop.
(D) In the years that the new technique had been in use, several safeguards have been added to prevent the contamination of nearby water.
(E) All of the aquifers near which the proposed technique would be employed are used or will soon be used to provide drinking water for their surrounding communities.

(A) Some of the countries currently using the new technique have only been doing so for two years or less.
If only some countries have been using it for a short time, it logically implies that other countries have been using it for a much longer time. Because those long-term users still have not reported any issues, the mining companies' premise remains largely intact.
(B) Other widely-used techniques used to procure oil have led to even worse contamination issues than what environmentalists predict could happen with the new technique
Comparing the new technique to older, dirtier methods might make the new technique look better by comparison, but it does not actually address whether this specific new technique is inherently safe to use near aquifers.
(C) The countries currently using the technique are so dependent on oil revenue that they are unlikely to report any problems that might require them to stop.
The mining companies conclude that the technique is safe based entirely on the fact that no environmental problems have been reported. Since they are likely covering up any damage to keep the money flowing, the fact that they haven't reported anything doesn't actually prove that the method is safe.
CORRECT
(D) In the years that the new technique had been in use, several safeguards have been added to prevent the contamination of nearby water.
This choice actually strengthens the argument instead of weakening it. If engineering safeguards have actively been added over the years to prevent water contamination, it gives us more reason to believe that the technique is now safe to proceed with.
(E) All of the aquifers near which the proposed technique would be employed are used or will soon be used to provide drinking water for their surrounding communities.
Showing that the consequences of a mistake are severe does nothing to prove whether a mistake is actually likely to happen.
Ans C

VERITAS PREP OFFICIAL SOLUTION:
Look at the gap in logic in this problem: the environmental groups are worried that contamination might HAPPEN but the conclusion is based upon the idea that no contamination has been REPORTED. But does "not reported" mean "didn't happen"? Not necessarily. Choice C seizes on that discrepancy and shows why contamination could happen but not be reported. Choice C is therefore correct.
