Infotek, a computer manufacturer in Katrovia, has just introduced a new personal computer model that sells for significantly less than any other model. Market research shows, however, that very few Katrovian households without personal computers would buy a computer, regardless of its price. Therefore, introducing the new model is unlikely to increase the number of computers in Katrovian homes.

Which of the following is an assumption on which the argument depends?

A:Infotek achieved the lower price of the new model by using components of lower quality than those used by other manufacturers.

B:The main reason cited by consumers in Katrovia for replacing a personal computer is the desire to have an improved model.

C:Katrovians in households that already have computers are unlikely to purchase the new Infotek model as an additional computer for home use.

D:The price of other personal computers in Karovia is unlikely to drop below the price of Infotek`s new model in the near future.

E:Most personal computers purchased in Katrovia are intended for home use.

615. 题目类型：假设题

题目场景：K 国的一个电脑制造商推出了一种新的电脑，比其他任何电脑售价都要低。但是市场研究发现，在还未拥有电脑的家庭中，无论电脑是什么价格，几乎没有人会选择购买一台。因此推出新电脑不会提升 K 国家庭的电脑拥有数量。问得出结论依赖的假设是什么

题目推理：前提：市场研究发现，在还未拥有电脑的家庭中，不会因为电脑价格低就去买一台结论：低价新电脑的上市不会提升 K 国家庭的电脑拥有数量

我们可以看出前提和结论明显讨论范围不一致，前提：还未拥有电脑的家庭，结论：K国家庭，因此gap就在有电脑的家庭

选项分析：

A :Infotek 使用了成本更低的零件来组装新电脑。这和已拥有电脑的家庭是否会购买新电脑没有决定性的联系。 

B :在 K 国消费者更换电脑的理由中，对于升级的电脑的需求是最主要的原因。更换电脑并不会改变拥有电脑的数量，因此与题目无关。

C :正确答案

D :其他电脑的预期价格大概率不会比 infotek 的低价新电脑更低。这与消费者是否购买新电脑无关，

E :大部分 K 国电脑都是为个人使用设计的。与题目无关
