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

答案是E。请问这选项是什么意思啊？
这题的意思是说指出推理错误么？

谢谢各位哦、、、

题意是说要想保护老虎不灭绝，就要禁猎，那些禁猎法令得以实施了，the survival of tigers in the wild will be ensured.
critical point：把老虎的生存阻碍拿掉了就真的利于老虎survival吗？不一定，可能是因为虎的繁殖能力下降等内因而致使数量变少，这样的话，禁猎也不一定起到作用。E

题目是说在以下哪项的基础上最能有效地指出这个argument推理的薄弱点。
E是说将对老虎生存有威胁的因素去掉是老虎生存的保证，而原文犯的错误就是这个。

谢谢两位NN的帮助哦。。。

这题我错选了C，当时想，猎人猎不一定都成功啊，如果没有成功那就连impedement都没有构成，更不用说E了，所以当时觉得这题没有想过猎人杀虎成功机率是多少，换句话说我理解成题里没有考虑到猎人是否真的是虎的危胁，但是文章第一句话说Unless tiger hunting decreases, tigers will soon be extinct in the wild. 所以猎人肯定至少是危胁之一了。。。。

最后一个包括了所有因素，而不是单独的一个。AC 都是个别指出。
