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.

95. 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. Argument Construction

Situation        A public official argues that increased catches show that marine fish are no longer endangered. An environmentalist attacks the position and cites technology as the cause of the increased catch. (The same as the previous item.)

Reasoning: What conclusion do the environmentalist's statements support? The environmentalist casts doubt by saying the commissioner
                    would have the public believe that the increased catch shows that
                    the fish are no longer endangered; the phrasing indicates that environmentalist believes just the reverse. The environmentalist does believe the marine fish are endangered, and, after attacking the commissioner's argument as
                    specious, or false, and offering an analogy to make that argument look ridiculous, the environmentalist gives an alternate explanation for the increased catch that is consistent with that belief.

A          The encroachment of people on nature is not examined.

B           No methods to determine the number are discussed in the statements.

C           The environmentalist compares the two arguments, not the two proportions.

D          The fish are not said to be inedible.

E           Correct. This statement properly identifies a conclusion supported by the environmentalist's statements: the marine fish are endangered.     _

The correct answer is E.

答案为什么不是A

最后一句说”The real cause of the increased fish-catch is a greater efficiency in using technologies that deplete resources.“

因此我是这样理解的

not marine fish no longer endangered，but using technologies －－>increased fish-catch

adai

A也有些问题increasing encroachment of people on nature的确在原文中没有明确提到

若把A改成
        The use of technology is the reason for the increased fish-catch 对吗？

还是应为”specious argument“这个指示，表明此题关键的推理是increased fish-catch －－>this resource is no longer endangered；且environmentalist反驳了这个推理；

因此“increased fish-catch” 不能推出 “this resource is no longer endange”

推里不成立，就能否定原推理的结果吗？ 就能说"Marine fish continue to be an endangered resource"吗

我个人觉得答案E没有疑义.文章的最后一句话的确说了 using technologies that deplete resources-->increased fish-catch. 但注意这里technologies的额外条件"that deplete resources",option A: The use of technology is the reason for the increasing encroachment of people on nature.武断地说 use of 所有的technologies是错误的;)

抓住题干的主要结论(只有一个).

perpetual007

句子A本身也是对的，但并不是环保主义者想表达的主要观点。

注意看问题：95. The environmentalist's statements, if true, best support which of the following as a conclusion?

adai

答案是E没有问题了

只是解体思路上我需要理一下

谢谢楼上各位的答复

这一题的思路还不是很清楚啊!

请问

marine fish caught↑ → resourse no longer endangered

efficiency technologies that deplete resources → marine fish caught↑

如何推出(E)  Marine fish continue to be an endangered resource.???

rebeccabelle

其一，抓住题目的结论（只有一个）。同意Hollygrail.

其二，分析题目：*（结论）这种观念是错的：即多捕鱼，表明此资源不再受威胁。*（论证）类比一下，如同多砍伐森林，此资源就表明不受威胁一样，不确切。*（论证）提供解释，是捕鱼技术提高导致捕鱼量增大。

请重点关注结论。题目中的"would have the public believe that"环境保护主义者的观点与之相反。即这种资源还是受威胁的。

rebeccabelle

紧紧抓住结论

呵呵
