GWD7-Q30:
weaken
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 [url=]Ink-jet printers in regular use frequently need new ink cartridges, and Printwell’s printers only accept Printwell’s ink cartridges.[/url]
B [url=]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.
[/url]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.
答案是Ａ，请教一下，大概怎么理解的，Ｂ呢，其它的怎么排除？

division sales = cartrige sales + printer sales
printer sales increase -> cartrige sales increase -> cartrige sales
revenue increases (at constant price)

题目说的是打印机销量上升了,但是单价因为竞争会下降,而成本却不会下降,所以收入会减少.
A选项:该厂产的打印机只能用该厂产的特定的墨盒,打印机卖的多了,墨盒也卖的多了,但墨盒的价格不下降,所以由卖墨盒得的revenue上升,会弥补打印机的loss

但是我觉得B选项也可能呀~
题目里说，主要是因为不能再bring down the cost of manufacturing， 才导致revenue不能上升
但是根据B选项，因为公司price下降了，所以retail cost 也得以下降~而导致total cost是下降的（manuafacturing cost+marketing cost）~所以公司的revenue也应该是上升的呀~
怎么排除B选项呢？

B选项实际上support了profit会下降
题目里说，主要是因为不能再bring down the cost of manufacturing， 才导致revenue不能上升
（revenue=cost+profit（我刚刚也求助了一道类似的题才被NN提醒过TAT）=salesXprice revenue 题目说尽管sales上升但是由于竞争price下降所以revenue没有增加 而又不能降低cost所以profit下降→ the Ink Jet Division must be providing the company with much smaller than it used to）
total cost是（manuafacturing cost+marketing cost）
YES
因为公司price下降了，所以retail cost 也得以下降
（price下降marketing cost不一定下降，而由于sales的增多一般marketing cost可能会增多。当然其实这都是想多了，原文和选项都没有说这一点。B选项是讲marketing cost占了price的相当一部分，这样其实是在说profit会更小了）
