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：
请问张慧雯老师，这题我看懂了，现在说说我选项间排除的思路，问题问的是：这个公司用pc替代盐的利润，找无关的 首先我觉得这题和钱有关的肯定对ac没问题，bde觉得都和钱和利润没什么关系，不知道如何排除bd选项。b谈的是设备合不合适的问题，可以理解为如果不合适就会浪费钱吗？d又如何排除呢？bde纠结。
