Environmentalist: The commissioner of the Fish and Game Authority would have the public believe that increases
in the number of marine fish caught demonstrate that this resource is no longer endangered. This is a specious
argument, as unsound as it would be to assert that the ever-increasing rate at which rain forests are being cut
down demonstrates a lack of danger to that resource. The real cause of the increased fish-catch is a greater
efficiency in using technologies that deplete resources.
The environmentalist's statements, if true, best support which of the following as a conclusion?
(A) The use of technology is the reason for the increasing encroachment of people on nature.
(8) It is possible to determine how many fish are in the sea in some way other than by catching fish.
(C) The proportion of marine fish that are caught is as high as the proportion of rain forest trees that are cut
down each year.
(D) Modern technologies waste resources by catching inedible fish.
(E) Marine fish continue to be an endangered resource.
