GWD一题

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?d  a

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.

答案是A，不明白题目是什么意思

结论：尽管打印机的销售量上升，ink jet 部门的给公司做出的贡献将比以往他们做出的少（注意题目由，ink jet printer 推出ink jet division）

evidence:ink jet printer 销售下降了，由于成本下不来

weaken：ink jet printers 经常要换针头，且只接受自己的针头（因为针头的销售额的上升，所以ink jet division 给公司的贡献不会比以前少）

题目说的是：打印机的销量增加了，但利润并没有增加，因为单价被迫降低了。而且成本还降不下来，所以，这个部门给公司做得贡献要少了。

A的意思是说因为打印机销量增加，那么这种打印机只接受的针头的销量也就增加了，所以这个部门做得贡献也不会少。

好像跟上面那位说的差不多哈。。。呵呵。。。我也是新手。。不好意思
