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:重點在the impact on company profits

1. 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?
               
2. To what extent is the equipment involved in preserving animal hides using common salt suitable for preserving animal hides using potassium chloride?
               
3. What environmental regulations, if any, constrain the disposal of the waste generated in reprocessing the by-product of potassium chloride?
               
4. How closely does leather that results when common salt is used to preserve hides resemble that which results when potassium chloride is used?
               
5.  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

对于这里，我很不明白，由于自己的逻辑思维和老美相差很大，所以很痛苦。。唉。。。

A：这里因为说要有impact on profit的话，那么只要有利润的话，成本肯定是一个很大的因素。

B：字面意思还不懂呢，请NN给解答

C环境法规在限制处理废料上面限制了什么？限制的多，就说明成本会大，之所以要换另外一个方法就是因为规则增加了成本。。

D：这2个方法在保存hide上面有多么接近？和利润有关，要是不接近，那么产品会不会好。

E：问PC中的一种化学咚咚是不是和使用盐的化学咚咚是一样有效的保存兽皮的？这怎么一看就是有关的啊？

不理解啊

请帮助
