标题: OG12 CR 第115题
Caterpillars of all species produce an identical hormone called “juvenile hormone” that maintains feeding behavior. Only when a caterpillar has grown to the right size for pupation to take place does a special enzyme halt the production of juvenile hormone. This enzyme can be synthesized and will, on being ingested by immature caterpillar, kill them by stopping them for feeding.

Which of the following, if true, most strongly supports the view that it would NOT be advisable to try to eradicate agricultural pests that go through a caterpillar stage by spraying croplands with the enzyme mentioned above?

(B) Many agricultural pests do not go through a caterpillar stage
(C) Many agricultural beneficial insects go through a caterpillar stage

我选了B，答案选C，我理解为什么选C可以，但为什么B不能选呢？这道题目在讨论杀害虫的问题，B不是更直接么？

请问一下这题的 (E) Although the enzyme has been synthesized in the laboratory, no large-scale production facilities exist as yet. 为什么不可以的。。OG 的解释是现在不能生产不代表以后。。有点模糊。。。。求解释~~

E的选项不是针对问题的情况讲的吧。。

According to OG:
E is wrong because：The mere lack of current production facilities does not mean that it would be inadvisable to
develop and use the spray in the future.
However in my opinion, I think E is not the right answer, because it contradict the premise
stimulus: cause enzyme can kill all the pests that go though a caterpillars stage,
conclusion: enzyme should be used to eradicate pests
potential assumption: there are enough synthesized enzyme
For E: there is no enzyme ---> So it is wrong

But I am not sure whether there are some flaws in my reasoning,
If so, please corret me``thanks a lot!

问题所问是（主要看粗体）根除什么样的pest呢，是go through a caterpillar stage的pest。。。
Which of the following, if true, most strongly supports the view that it would NOT be advisable to try to eradicate agricultural pests that go through a caterpillar stage by spraying croplands with the enzyme mentioned above?

(B) Many agricultural pests do not go through a caterpillar stage－－－很多pests没有go through a caterpillar stage－－－跟问的就没关系。都没有go through a caterpillar stage，这种enzyme就对根除这种pests没用了。
(C) Many agricultural beneficial insects go through a caterpillar stage－－－有益的insects也go through a caterpillar stage了，这种不能根除啊。

LS 正解问题问的是pest that go through a caterpillar stage

总结一下，遇见这种两个选项都可以的，一般重新读下题干就可以排除选项的。

B选项irrelevant，题目中明确说的是that go through a cateroilliar stage.
打个简单的比方：问国家这项政策对文艺青年有什么好处？你答大多人不是文艺青年（而是2B青年，瞎扯的哈）这不是牛头不对马嘴吗？？！

我觉得这个题目是另一种形式的weaken
直接找能weaken题干中结论部分的

作者: Kya 时间: 2013-9-29 00:19
还有一种理解就是题干not advisable作”不可取，不明智“解释，B项暗示方案可能没用，但不是不可取，不可取要找方案的负面影响！
