答案是E,不是很明白,段落的逻辑关系也没怎么弄懂,似乎A也有道理~~
GWD-8-Q38:
Unless tiger hunting decreases, tigers will soon be extinct in the wild. The countries in which the tigers’ habitats are located are currently debating joint legislation that would ban tiger hunting. Thus, if these countries can successfully enforce this legislation, the survival of tigers in the wild will be ensured.
The reasoning in the argument is most vulnerable to criticism on the grounds that the argument
A. assumes without sufficient warrant that a ban on tiger hunting could be successfully enforced
B. considers the effects of hunting on tigers without also considering the effects of hunting on other endangered animal species
C. fails to take into account how often tiger hunters are unsuccessful in their attempts to kill tigers
D. neglects to consider the results of governmental attempts in the past to limit tiger hunting
E. takes the removal of an impediment to the tigers’ survival as a guarantee of their survival
请NN们指教,非常感谢!!
Unless A, B, 是一个典型的必要条件的形式, A是B的必要条件。
也就是说,想要达到结果B(野生老虎存活),必须有条件A(停止猎虎)。反过来,满足了A(停止猎虎),不一定能达到B(野生老虎存活)。别的因素也会造成B,比如老虎栖息地生态变化等等。
E说的就是把取消野生老虎存活的阻挠之一当成了达到目的的全部所需。完全符合上面的分析。
A说的warrant, enforce什么的,都基于太多的假设和别的因素,可以说是无关选项。
