95    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.

(B)       It is possible to determine how many fish are in the sea by 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.

答案是E。 但题目中说专家通过类比反驳了“通过捕捉数量说明鱼类并没有频危”，但并没说鱼类就是endangered resource啊。

无法通过捕捉数量说明存在鱼类的鱼类多，即更加无法通过捕捉数量说明鱼类的数量（连多或是少都无法说明，何况数量？），不正是说明B是对的吗？

本来海洋鱼类资源就被认为是an endangered resource（从一句话得出），A说这个资源不再是an endangered resource了，B驳斥了A的说法，那么是不是B认为它还是an endangered resource。

increases in the number of marine fish caught demonstrate that this resource is no longer endangered.说明他原来是endangered, 作者说是因为机器设备的efficient的提高而导致的捕鱼量增加，

而不是由于鱼本身的数量增加导致的捕鱼量增加， 所以在原来的基础上这种鱼的数量会减少的更快，因为本身濒临灭绝，捕的又多，最终还是endangered.
