B14. The following appeared in a memorandum from a company’s marketing department:

“Since our company started manufacturing and marketing a deluxe air filter six months ago, sales of our economy filter—and company profits—have decreased significantly. The deluxe air filter sells for 50 percent more than the economy filter, but the economy filter lasts for only one month while the deluxe filter can be used for two months before it must be replaced. To increase repeat sales of our economy filter and maximize profits, we should discontinue the deluxe air filter and concentrate all our advertising efforts on the economy filter.”

1.Cum hoc, ergo propter hoc 同时出现不表示因果

2. False dilemma 错误的两难选择 (not necessary Either produce deluxe air filter Or stop producing that. Could use other alternative ways such as increasing the price of deluxe air filter)

请问还有其他吗？下面这一点如何攻击?

The deluxe air filter sells for 50 percent more than the economy filter, but the economy filter lasts for only one month while the deluxe filter can be used for two months before it must be replaced.

3.题目只比较了单价，也许高级货的销量远超过低级货，那么即使低级货销售周期短，还是不划算。

4.低级货寿命短，但有可能别人不再买了。比如转向其他厂商

再补充一个，loss and benefit analysis, whether the benefit of this method can offset the loss of this method.
