T-4-Q15
TrueSave is a mail-order company that ships electronic products from its warehouses to customers worldwide. The company’s shipping manager is proposing that customer orders be packed with newer, more expensive packing materials that virtually eliminate damage during shipping. The manager argues that overall costs would essentially remain unaffected, since the extra cost of the new packing materials roughly equals the current cost of replacing products returned by customers because they arrived in damaged condition.
Which of the following would it be most important to ascertain in determining whether implementing the shipping manager’s proposal would have the argued-for effect on costs?

A.    Whether the products shipped by TrueSave are more vulnerable to incurring damage during shipping than are typical electronic products.
B.    Whether electronic products are damaged more frequently in transit than are most other products shipped by mail-order companies
C.    Whether a sizable proportion of returned items are returned because of damage already present when those items were packed for shipping
D.    Whether there are cases in which customers blame themselves for product damage that, though present on arrival of the product, is not discovered until later
E.     Whether TrueSave continually monitors the performance of the shipping companies it uses to ship products to its customers


作者意思就是原来的成本=运输成本+退还给顾客的补偿费用，也等于现在的成本=原来运输费+好的包装费，而补偿费用和包装费是大致相等的，所以unaffected.答案选C，逻辑是，如果回答NO，那么换了好的包装能够eliminate the damage，所以就能减少退货费用，但是有一个问题很奇怪，如果换了包装之后，现在的成本就与退不退货无关了吧？？


T-4-Q20 天山-7-22
The violent crime rate (number of violent crimes per 1,000 residents) in Meadowbrook is 60 percent higher now than it was four years ago. The corresponding increase for Parkdale is only 10 percent. These figures support the conclusion that residents of Meadowbrook are more likely to become victims of violent crime than are residents of Parkdale.
The argument above is flawed because it fails to take into account
A. Changes in the population density of both Meadowbrook and Parkdale over the past four years.
B. How the rate of population growth in Meadowbrook over the past four years compares to the corresponding rate for Parkdale
C. The ratio of violent to nonviolent crimes committed during the past four years in Meadowbrook and Parkdale
D. The violent crime rates in Meadowbrook and Parkdale four years ago
E. How Meadowbrooks’ expenditures for crime prevention over the past four years compare to Parkdale’s expenditures.




答案选D。但是我选的是B，因为犯罪率不是还要考虑人口吗？为什么不考虑这个方面？

我的第二题不选B的原因是与题干不相关，只有D是直接揭示与题干相关的内容。楼主你想啊，就如b答案所考虑的方面，其实每一个题都还需要考虑很多方面的问题，这么一来题目就没有外延了。所以一定要选直接相关说这个题的，不要发散思维。

原文说：要不要采用贵的包装材料；有没有效
A.    Whether the products shipped by TrueSave are more vulnerable to incurring damage during shipping than are typical electronic products. 说一般货物比ELEC更易受损
B.    Whether electronic products are damaged more frequently in transit than are most other products shipped by mail-order companies说elec 比其他更容易受损 most other绝对化
C.    Whether a sizable proportion of returned items are returned because of damage already present when those items were packed for shipping 多少比例的货物被挽救 和原文有没有效有关
D.    Whether there are cases in which customers blame themselves for product damage that, though present on arrival of the product, is not discovered until later说尽管货物来了，顾客还是要责备 无关
E.     Whether TrueSave continually monitors the performance of the shipping companies it uses to ship products to its customers TS是否监视货运公司 无关

虽然是这样说没错，但是题干中问的也是fails to take into account ，也就是说作者忽略了某一方面。。。。我就是这样才觉得B是潜在的影响因素。。。。。。

我发现我对题目的意思理解有偏差了，题目问的是哪个选项能评价这个方案是否取得预期的效果，即unaffected or not，而不是我理解的降低成本
还有一个地方就是，是那个等式写错了，newer,more expensive materials 代表原来也有包装费，所以是运输费+原包装+赔偿金=运输费+贵包装（贵包装=原包装+extral costs,而extral costs=赔偿金，所以等式是大致相等的），如果C选项的答案是YES，那么cost会受到影响，因为右边的等式还要加上赔偿金，如果答案是NO，那么cost不会受影响，也就是原文的叙述是正确的。

应该就是这样理解的。
