GWD-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？？
