标题: VERBAL REVIEW-54 [打印本页] 作者: jenny1989117 时间: 2010-7-9 20:42 标题: VERBAL REVIEW-54 Gmat Review 上的一道题目,主要不明白E选项为什么不对如果C是对的话,E也可以解释为不同的化学物质的成本可能不同??? 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 the use, and in consequence, Tanco is considering a plan to use potassium chloride in place pf 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 pf using potassium chloride in place pf common salt,it would be important for Ranco to research all of the following EXCEPT: AWhat difference,if any, is there between the cost of common salt needed to preserve a given quantity pf animal hides and the cost of the potassium chloride needed to preserce the same quantity of hides? BTo what extent is the equipment involved in preserving animal hiodes using common salt suitable for preserving animal hides using potassium chloride? CWhat environmental regulations,if any, constrain the disposal of the waste generated in reprocessing the by-product of potassium chloride? DHow closely does leather that results when common salt is used to preserve hides resemble that which results when potassium cholride is used? EAre the chemical properties that make potassium chloride an effective means for preserving animal hides rthe same as those that make common salt an effective means for doing so?作者: nanisoga 时间: 2010-7-9 21:17
同问,感觉E好像更好一点,不懂为什么是C。。。作者: 小伊YSY 时间: 2011-8-13 01:00
