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. Answer: a

我选的是E。
因为打印机卖的多,可以推出墨水也就卖得多。但是题中没有给墨水卖得多是不是就利润多,万一和打印机一样也降了价,没有什么利润空间呢?这就没法推出说墨水卖得多就一定利润增多。所以我觉得这个选项是ETS设的一个圈套。
而且这个选项还有一个我看来最明显的换套,题干说这个公司生产和销售喷墨打印机和墨水,而后来讲的是喷墨打印机如何,结论是所以喷墨打印机这个部门就不如以前了。可是没有任何地方提示,喷墨打印机和墨水就一定是一个division。也就是说即使墨水卖得好,利润高,也可能和这个JET PRINTER DIVISION没什么关系。 虽然从名称和常理上想应该是,但是题干不有告诉我们的,我们就一般应该当它不存在。
我选E的原因在于,这道题的结论是说:这个部门对公司的贡献不如以前。如果有公式表示就是
喷墨打印机部门利润 / 公司总利润, 同时 公司总利润 = 各部门利润的总和。
从题中可以看出来这个公司是以产品类型而划分部门的,而E告诉我们其它部门的利润不如喷墨打印机部门,也就是说公司总利润在下降,而同时喷墨打印机部门的利润是最高的,也就是占比是最大的。当然就可以推出说题的结论是不对了。
大家看看我这样想对不对。不管是砖也好瓦也好,看到有回音就比什么都好。
下面是关于这题以前的讨论联接,因为是老早的贴,怕NN们注意不到有新问题,所以再发一次,不好意思。
