Q22: TTGWD2-Q17:
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?





答案选的是E，分析之后我排除了几个选项 A 和C，但是对于D选项非常不理解，我觉得D选项考虑制造皮革的结果是否相似如何能判断成本的变化呢？

自己顶一下~

D主要是说采用了新方法以后是否能达到相同的效果。如果达不到用common salt时相同的下过的话，可能会影响产品的销售，继而影响company profits。

照这样解释的话，E选项和D选项考虑的不是同一个方面嘛?都是考虑最后的效果是否相同，如果不同就会影响利润

DE很像啊~~
