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。

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?
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
