Printwell’s Ink Jet Divisionmanufactures ink-jet printers and the ink cartridges they use.  Sales of its ink-jet printers haveincreased.  Monthly revenues from thosesales, however, have not increased, because competition has forced Printwell tocut the prices of its printers. Unfortunately, Printwell has been unable to bring down the cost ofmanufacturing a printer.  Thus, despitethe increase in printer sales, the Ink Jet Division must be providing thecompany with much smaller than it used to.
Which of the following, if true, mostseriously weakens the argument?
A.   Ink-jet printers in regular use frequentlyneed new ink cartridges, and Printwell’s printers only accept Printwell’s inkcartridges.
B.   Unlike some competing companies, Printwellsells all of its printers through retailers, and these retailers’ costs accountfor a sizable proportion of the printers’ ultimate retail price.
C.   Some printer manufacturers have been forcedto reduce the sale price of their ink-jet printers even more than Printwellhas.
D.   In the past year, no competing manufacturerof ink-jet printers has had as great an increase in unit sales of printers asPrintwell has.
E.    In the past year, sales of Printwell’sink-jet printers have increased more than sales of any other type of printermade by Printwell.

LZ你好，首先我来解释下A的正确性：   Ink-jet printers卖的好但价格下调是影响商品利润的直接因素。 但Ink Jet Division对公司的总贡献并不仅限于Ink-jet printers的利润，按A的说法，Ink-jet printers销量好会带动Printwell’s ink cartridges的销量  而Printwell’s ink cartridges的价格又不受市场上竞争对手的影响，所以Printwell’s ink cartridges的利润值会大大提高，从而使nk Jet Division对公司的总贡献大大提高。

已知，printer降价，销售量增多，降价幅度可能大过销售量增多带来的益处，暂且假设printer会亏损，这时，cartridge如果和printer捆绑销售，那么cartridge销售量就会增加，而它的售价没变，因此会带来更多的收益，弥补printer的不足。这样一来，这个公司的销售额还是可能增加。D错，因为D只是将这个公司与其他公司横向比较，并不能提供这个公司将盈利的可能。题干中没有给出其他公司的盈利情况
