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.
background: Division制造打印机和墨盒
尽管打印机销量增加，打印机带来的销售额却降低因为打印机的单价降低了。所以divisin对于公司利润的贡献一定比以前少了。问weaken
choice a, 打印机经常要换墨盒，并且只接受原厂的墨盒。correct，profits来自两部分：打印机的和墨盒的。打印机销量低，但是墨盒销量高就可以弥补
