http://7sage.com/lsat_explanations/lsat-18-section-4-question-14/At first, I thought the answer might be (D) since before I saw the answer choices I noticed that there is a problem in assuming that atmospheric ozone levels are equal in every global region. So I expected that the answer must be something like the ozone levels are getting higher in polar region and lower in other regions so that global ozone levels are remaining constant.
However, the answer choice (D) is exactly opposite to my expectation, saying that ozone levels are increasing in other regions and decreasing in polar region. But can this undermine the government official's dismiss on the concern that "polar" marine life is damaged? If ozone level in polar region is decreasing since quantity of ozone is shifting away from the polar cap (as (D) says), there would be no harm to polar marine life.
Or did I wrongly catch the argument of the government officials? Is the argument of the gov't official simply that protective ozone layer over the Antarctic is not decreasing?
Comments
The gist of the argument from the government officials is that the decreasing of the protective layer of the Antarctica is not a point of concern. Why? Because statistics indicated that global atmospheric ozone levels remained constant.
D) undermines the government official's argument, but showing that, sure, even though statistics indicate that atmospheric ozone levels remained constant, the decreasing of the protective layer of the Antarctica IS STILL a grown concern.
