4.     Which of the following best completes the passage below?

Sales campaigns aimed at the faltering personal computer market have strongly emphasized ease of use, called user-friendliness. This emphasis is oddly premature and irrelevant in the eyes of most potential buyers, who are trying to address the logically prior issue of whether______

(A) user-friendliness also implies that owners can service their own computers

(B) personal computers cost more the more user-friendly they are

(C) currently available models are user-friendly enough to suit them

(D) the people promoting personal computers use them in their own homes（E）

(E) they have enough sensible uses for a personal computer to justify the expense of buying one

现象:销售电脑时更多强调使用的人性化,强调功效

结论:这个策略有失偏颇

依据:因为不知道消费者能够清楚的知道用处在哪(E)

假设消费者根本无法判断电脑的功效在何处(即对E取非),那么我们销售的时候再强调功效都是没有用处的.

对E取非削弱结论.正确选项.

而B是个无关项

个人观点~

我和楼主一样选了B, 现在看大家的分析讨论，觉得E的确也不错。但是我当时选B的理由是，在潜在买家的

眼里，价格比是不是user friendly要重要。如果越是user friendly 越贵的话，那么也是不会买的。不知道这样的理解是对B选项字面理解的错误还是理解正确，但依然不如E好呢？
