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.

A正确：printer的销量增加，由于它的printer只能采用自己的墨盒，所以，虽然printer的价格降低，但仍然有可能通过销售出去更多的墨盒而比以前更挣钱，所以这就weaken了结论。

C错误：其他厂商的printer的价格更低，无法对文章的结论起到削弱作用。

C is irrelevant. Let me give you an example: A's salary is cut, therefore A's total income must be less. You can argue by saying B's income is cut even more because the original argument is not about comparing A and B. Back to the question. If the conclusion is that the company must be worse than other companies, C will be relevant.

CR requires you stick to what is within the logic reasoning of the argument.

生产喷墨打印机和墨盒，打印的利润下降，由于销量增长了，使得墨盒必然用得多了，因此墨盒的利润增长

a的解释是不是多了自己的理解，a只说：printer只用自己的墨盒，但没有说墨盒的销售增加的利润，足够cover销售printer减少的利润,然后还有盈余。

而且墨盒的价格到底有没有也下降，也不知道，怎么能够推论出

despite the increase in printer sales, the Ink Jet Division must be providing the company with much smaller than it used to.

问一个与选项无关的问题~

Thus, despite the increase in printer sales, the Ink Jet Division must be providing the company with much smaller than it used to.

这里的much smaller是指的什么？？如果是钱的话，不是应该用less？？

如果不是钱，那指代什么？
