IMO C

(C)

These questions are routinely low quality.

I'm between B and C but C is my final answer.

Until recently, the scholarly consensus was that few marine species are approaching extinction. Closer examination of marine species near the island of West Indies, 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 West Indies 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 West Indies 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.
A, D, and E can be eliminated at first sight bcz they are supporting to the given statement.
B is also out of scope
Final answer is C.

answer is C
as it tells that If systematic sampling were a more common practice in marine environments,

then there would likely be more evidence supporting the hypothesis that many marine species are approaching extinction.
