Solution

The correct option is B They have drawn premature conclusions concerning a crisis in amphibian populations from recent reports of declines.
Option D is the correct answer. The people concerned over the population decline of the amphibians drew conclusions over the recent reports, that have turned around with time, and no longer pose the same threats as before, thus, making their predictions useless. The statements of options A,B,C and E are incongruent with the text, which are not completely explained here. Therefore, they are incorrect.

Q. The concentration of polychlorinated biphenyls (PCB, an organochloride contaminant) in many fish populations has been declining, since a ban on their production was instituted in the late 1970s. PCBs remain a potential problem, however, because they are lipophilic and are known to biomagnify. Based on this knowledge,
