标题: ASK FOR HELP---ANOTHOR LOGIC PROBLEM [打印本页] 作者: evelyn205205 时间: 2011-1-27 23:32 标题: ASK FOR HELP---ANOTHOR LOGIC PROBLEM 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?
THE ANSWER IS E

偶选E.
A. 成本的考虑 B. 对现有设备是否能和potassium chloride匹配的考虑 C. 法律法规的考虑 D. 对产品的考虑 以上都需要考虑。
但是，对于新的原料是否能和原有原料产生同样的结果（the same as，关键在“同样”两个字）,不需要考虑。如果同样的量产生的结果不一样，就多用/少用点呗，最终看的是对于成本的影响。
