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 contributing less to the company's profits than it used to.
Which of the following, if true, most seriously weakens the argument?
Ink-jet printers in regular use frequently need new ink cartridges, and Printwell's printers only accept Printwell's ink cartridges.
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.
Some printer manufacturers have been forced to reduce the sale price of their ink-jet printers even more than Printwell has.
In the past year, no competing manufacturer of ink-jet printers has had as great an increase as Printweil in unit sales of printers.
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.
这题还是错在没看懂，原来是在讨论打印机和墨的关系。原文说即便打印机销量上升，但是由于其单价的下降，打印机+墨这条产品线不会对利润有多大贡献了。A选项提到了墨是专用的，买打印机就必须用这种墨水，所以打印机销量上升，墨也上升，而且墨的价格又没有被限制。错选E，其实一般CR看到选项里拿过去某个事情做样本基本也是错，因为这种样本没什么代表性，有可能是特例。
