GWD7-Q30:

Printwell’s Ink Jet Division manufactures ink-jet printers and the ink cartridges they use.Sales of its ink-jet printers have increased.Monthly revenues from those sales, however, have not increased, because competition has forced Printwell to cut the prices of its printers.Unfortunately, Printwell has been unable to bring down the cost of manufacturing a printer.Thus, despite the increase in printer sales, the Ink Jet Division must be providing the company with much smaller than it used to.

Which of the following, if true, most seriously weakens the argument?

A.Ink-jet printers in regular use frequently need new ink cartridges, and Printwell’s printers only accept Printwell’s ink cartridges.

B.Unlike some competing companies, Printwell sells all of its printers through retailers, and these retailers’ costs account for a sizable proportion of the printers’ ultimate retail price.

C.Some printer manufacturers have been forced to reduce the sale price of their ink-jet printers even more than Printwell has.

D.In the past year, no competing manufacturer of ink-jet printers has had as great an increase in unit sales of printers as Printwell has.

E.In the past year, sales of Printwell’s ink-jet printers have increased more than sales of any other type of printer made by Printwell.


现在可以理解A是符合题意的答案,但是B为什么不对呢?如果不通过零售商销售的话,不就可以为厂家节省一些成本了么?

题目中没有告诉你不通过零售商你就不能自己假设,也就是不能

根据“常识”过度推理。
