标题: OG12补充材料第54题
Tanco, a leather manufacturer, uses large quantities of common salt to preserve animal hides. New environmental regulations have significantly increased the cost of disposing of salt water that results from this use, and, in consequence, Tanco is considering a plan to use potassium chloride in place of common salt. Research has shown that Tanco could reprocess the by-product of potassium chloride use to yield a crop fertilizer, leaving a relatively small volume of waste for disposal.

In determining the impact on company profits of using potassium chloride in place of common salt, it would be important for Tanco to research all of the following EXCEPT:

A. What difference, if any, is there between the cost of the common salt needed to preserve a given quantity of animal hides and the cost of the potassium chloride needed to preserve the same quantity of hides?

B. To what extent is the equipment involved in preserving animal hides using common salt suitable for preserving animal hides using potassium chloride?

C. What environmental regulations, if any, constrain the disposal of the waste generated in reprocessing the by-product of potassium chloride?

D. How closely does leather that results when common salt is used to preserve hides resemble that which results when potassium chloride is used?

E. Are the chemical properties that make potassium chloride an effective means for preserving animal hides the same as those that make common salt an effective means for doing so?

正确答案是E,但是我觉得D和E的性质是一样的,它们都是在说这两种物质对leather的影响。为什么E对而D错呢？？？

你要仔细读一下E，这个很疑惑人的
E：让potassium chloride 能够有效保存动物皮毛的化学成分和让common salt 能够有效保存动物皮毛的化学成分一样么？
这一点，其实除非你是好奇的化学爱好者，公司是没有必要知道的，反正有效就行。

thx 4 ur answer, but
E: 如果皮毛的化学成分改变的话有可能会影响到皮毛的质量进而影响到它的销量
这样E和D不都会影响该公司的profit吗...

1楼说的对
你仔细看E选项主语是chemical properties 让这两个方法都起作用的化学物质是不是同一个
换句话说E的意思是这两种保存方法所用的化学原理是不是一样
这个跟题目没有关系
并不是你说的皮毛的化学成分改变了那个是D的意思

u r right, the subject is chemical properties, and i thought it was the 'effective means' ( i need to pay more attention while reading

)
thx for pointing that out for me

我开始选的c,原文不是说Tanco could reprocess the by-product of potassium chloride use to yield a crop fertilizer吗？那么就不需要考虑c中的问题了吧，虽然有少量waste，但不是直接的by-product啊？

题中只说了可以做肥料，没说花费多少，如果环境管理收费少于做肥料的钱，倾向于选择被罚款，但是与此同时，可能造成更多费用，因而影响到profit

3楼大虾正解~~~

E选项相当迷惑人...make potassium chloride an effective means只是一个定语...即，在两者都是有效保存皮毛的条件下探讨两者的保存原理时候一样...

D选项讨论的是产品的质量问题，E选项说的是，在同等情况下（potassium chloride 和 salt 都是effective means ），达到相同目的时，生产过程中起作用的chemical properties是否相同。
profits由收入和成本决定，chemical properties与收入、成本无关。。。

阿西巴这题看了两次都把E给理解错了句子根本没看懂。。。。
和楼主一样以为DE其实不是一个意思嘛
结果E说的是 are the chemical properties...the same as...? 并且说了两者都是有效的

两者都有效，至于化学成分是否一样，不重要。管他是不是一样呢，有效就行啊。化学方法那么多
有人说那化学成分不一样可能会导致生产出来的leather不一样呢。。。。这你就自己加了一步了。。。

这道题其实并不是很好。

看一下题目：Impact on profit。所以决策的关键在于利润的高低。

C选项提到的法律的限制确实会影响这个决策，但这个影响不在于利润，而在于遵守法律。同时这个法律如果限制了Potassium的输出，那是无法影响profit和cost的，因为potassium本身就无法大面积使用。出题C的老师可能并不清楚Legal Compliance到底是怎么回事而盲目的认为Legal Compliance必然会影响cost和profit。

如果把C改成：What environmental regulations, if any, could potentially penalize the disposal of the waste generated in reprocessing the by-product of pottasium chloride那还稍微可行。

答案最好是C，虽然我知道E是正确答案，且E也确实不完美。

E的问题不在于Out of Scope。如果硬要说E是不行的，那也在于Unecessary Assumptions。E的不完美之处在于“Same”，就是这个化学成分在两个目标物质里是不是一样的。这个其实不需要一样，只需要effective就行，如果不effective，必然会影响profit和cost。诚然，即便effective也可以是不同的化学成分。

但是至少就我来看，E触及profit和cost，建立了一个不是太好的关系。而C是完全没有建立这种关系。

本人从事legal compliance这里，所以可能会对这个问题的词语使用非常较真。

选了C，虽然E很好，但是不懂C为啥讨论了中心论点？按我的理解这题讨论的是花费的问题，因为花费高才改成用氯化钾，C也没讨论花费啊.........
