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.
题干说Monthly revenues from Printwell’s ink-jet printers 没有increase, 但是the Ink Jet Division 不光生产Printwell’s ink-jet printers 还生产 the ink cartridges ,那么如果 the revenues from the ink cartridges 增加了的话,那么 就可以推翻the Ink Jet Division must be providing the company with much smaller than it used to.
LZ看选项中这部分Ink-jet printers in regular use frequently need new ink cartridges, ,注意frequently,经常需要换ink,所以卖出一个printer带动的ink的增加应该是很大的,而且文中没有提到ink的价格和成本问题,所以我们可以assume一般情况下,卖的越多自然是收入越高的,所以成功削弱了文中的结论
