Until recently, the scholarly consensus was that few marine species are approaching extinction. Closer examination of marine species near the island of Tasmania, however, revealed many factors, such as climate change and fishing, that may be contributing to the extinction of species thought to be safe. The rate of extinction of marine species may be just as high as that of non-marine species, but the lack of systematic sampling has disguised the trend.
Which of the following is most strongly supported by the statements given?
(A) There are many marine species near Tasmania that are nearing extinction.
(B) Scholars who analyze the possible extinction of non-marine species rely on systematic sampling to determine which species are endangered.
(C) If systematic sampling were a more common practice in marine environments, there would likely be more evidence supporting the hypothesis that many marine species are approaching extinction.
(D) The threat to marine species near Tasmania is more severe than the threat to marine species whose habitats are elsewhere.
(E) If the rate of climate change were arrested and fishing were curtailed, the rate of extinction of marine species would fall to a level far below that of non-marine species.

I think the answer should be C.
(C) If systematic sampling were a more common practice in marine environments, there would likely be more evidence supporting the hypothesis that many marine species are approaching extinction.
It is more of a paraphrasing of the last line of the argument. Because there was no systematic sampling done on marine species, we were not able to look at the fact that the rate of extinction of many marine species was just as high as that of non-marine species.
Options B, C and D are all not necessarily correct.
On Option A, we need to look closely at the words used in the argument.
'Closer examination of marine species near the island of Tasmania, however, revealed many factors, such as climate change and fishing, that MAY BE contributing to the extinction of species thought to be safe'.
The closer examination did not revealed that many species IN TASMANIA, are approaching extinction, it revealed the FACTORS that MAY BE contributing (we also don't know whether this contribution is minor or major) to the extinction of species thought to be safe. So i used this reasoning to eliminate A.

OFFICIAL EXPLANATION
C
The phrase "most strongly supported" indicates that this is an inference question. Note the careful wording in the passage: "may be just as high" and "may be contributing". Given language like that, the wording of the correct answer will probably not be very strong.
Choice (A) is too extreme. We know that the research was done near Tasmania, but not the specific results of that result as regards the species that live there. (B) confuses the issue. It sounds like systematic sampling is how marine species are measured, but we don't know if it applies to non-marine species, as well. Choice (C) is well supported. The rate of extinction of marine species is disguised by the lack of systematic sampling, so it makes sense that more systematic sampling would provide more evidence of species extinction. (D) is an unsupported comparison, as we aren't given any data comparing Tasmania to other areas. (E) is far outside the scope of the passage. The statements don't provide any information about how the rate of extinction would be slowed, especially relative to that of non-marine species. Choice (C) is correct.
