试题详情
题目：
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.
选项:
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:
E
提问：
想问BD，两个选项写的好绕感觉没有读懂；B中当时没看懂equipment指代的什么就错选了；E的意思是说的两个东西的chemical有效程度，心理推理了既然chemical的有效程度类似那么这两个对保护动物hides性能是一样的，就觉得能够支持原文啊；如果Pc的效能比盐低，也不划算啊从profit角度看的话。想请老师解析。
