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:
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?
To what extent is the equipment involved in preserving animal hides using common salt suitable for preserving animal hides using potassium chloride?
What environmental regulations, if any, constrain the disposal of the waste generated in reprocessing the by-product of potassium chloride?
How closely does leather that results when common salt is used to preserve hides resemble that which results when potassium chloride is used?
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?
except题 第一次见 全都要看
E 化学性质 是否一样 偏的最严重
请问C选项,和Profits有什么关系呢?
Tanco一直用盐来保护动物皮。由此会产生盐水垃圾。新环境法规提升了处理此类垃圾的收费。所以,Tanco打算用potassium chloride 代替盐。研究发现,Tanco其实可以用potassium chloride的副产品来制作肥料,最后只留 下一小部分垃圾需要处理。
注意题干的EXCEPT!!!!
A:用盐和用potassium chloride成本是否有区别
B:用盐和用potassium chloride需要的设备区别
C:环境法规是否对副产品处理有规定
D:两者作用产生的产品质量是否不同
E:使两者产生效能的化学特性是否一样
chemical properties 性质不重要 有效就行
profit=sale-cost,ABC影响cost,D影响sale
看与profits有没有关系
D为什么不正确?
题目问的是除了哪个不重要,其他的都重要。d肯定是重要的,如果把盐换成别的,影响了最终毛皮的质量,那肯定是不可行的
