PrepTest C2, Section 2, Question 25
Although Stillwater Pond has been polluted by farm runoff for years, several species of fish still live there. The local fishing guide says that "the most populous fish species in the pond is also the one that has adapted best to living in polluted water." So if, as recent studies suggest, the most populous fish species in the pond is the bullhead catfish, then it must be that the local fishing guide believes that the species of fish in the pond that has adapted best to living in polluted water is the bullhead catfish.

The argument above is most vulnerable to criticism on the grounds that it
takes for granted that the local fishing guide believes that Stillwater Pond has been polluted by farm runoff for years
fails to take into account the possibility that the catfish in Stillwater Pond had to adapt very little to survive in polluted water
fails to take into account the possibility that the recent studies on fish populations in Stillwater Pond are inaccurate
fails to take into account the possibility that the local fishing guide mistakenly believes that some fish species other than the bullhead catfish is the most populous fish species in Stillwater Pond
takes for granted that Stillwater Pond has only one species of catfish living in it
