### HideShow timer Statistics

A recent examination of the waters of the Southern Ocean showed a substantial increase in pollution levels, which is usually caused by routine oil spills during industrial drilling operations in the area. Last month, an article published in the biannual newsletter of a prominent environmental organization attributed this increase to the operations of Gaston Inc., an oil company with several large deep-water drilling operations. This claim is not undermined by the finding that none of Gaston Inc.’s oil plants in the Southern Ocean had any oil spills, because ____________.

A. most increases in the pollution levels of oceans take place because of deep-water drilling operations
B. oil usually floats several feet below the surface of the ocean rather than at the surface itself
C. pollutants that enter the ocean sometimes take decades to affect the marine environment
D. tankers that transport oil from drilling plants to offshore locations often develop leaks
E. calculated amounts of oil are sometimes deliberately discarded by oil plants to maintain water pressure in the area surrounding the plant

Hi..

PARA speaks about pollution caused by routine spills of oil and further claims that company X involved in deep water drilling operations is responsible for the increase in pollution due to spilling of oil. Although there are no leakages in drilling operations but still X is responsible..

OF COURSE, the answer is straight-
there has to be SOME other way through which X leads to oil spill.

D talks exactly this saying that tankers shipping oil from X often develop leaks

D

There is no oil spills and yet Gaston Inc., an oil company is blamed. So no oil spills observed during drilling operations.
There must be something else responsible for this pollution.
A. Here the passage eliminates this point. Plus this is a generalized statement trying to explain a specific event. Hence wrong
B. Oil may float or burn or do whatever it like.. what's it to my question .. eliminate.
C. it Doesn't matter how much time it takes.. irrelevant to the question... Eliminate.
D. Provides a perfect solution to why the Gaston INC. are responsible for the pollution in ocean. Looks good
E. The question stem states that there is no spill . Deliberate or not that's none of our concern.. Eliminate
Finally D is correct

B and C are certainly wrong.
E is incorrect b/c there is still a gap between oils discarded and the increase in the pollution levels. In other words, oil plants can discard oils without causing any pollution.
A is out b/c A just talks about the pollution levels in general while the passage discusses "the increase in pollution levels that is not caused by spills."
