[求助]天山-4-15麻煩!

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?

1. Whether the products shipped by TrueSave are more vulnerable to incurring damage during shipping than are typical electronic products.

2. Whether electronic products are damaged more frequently in transit than are most other products shipped by mail-order companies

3. Whether a sizable proportion of returned items are returned because of damage already present when those items were packed for shipping

4. 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

5. Whether TrueSave continually monitors the performance of the shipping companies it uses to ship products to its customers

答案是E

想請問一下解題思路?

謝謝

你的答案是错的吧？ 应该是C

原文说：mail-order公司要用更好的包装来运东西，以减少他们在运送过程中的损坏。而花销将不会上升，因为与以前的赔付抵消。

评价：东西是否在包装运送之前就已经坏了呢？（即是不是运送本身造成的损坏？）

如果是，则weaken原结论； 回答否，支持
