我来回答下这个  希望能帮到大家
The value of a product is determined by the ratio of its quality to its price. The higher the value of a product, the better will be its competitive position. Therefore, either increasing the quality or lowering the price of a given product will increase the likelihood that consumer will select that product rather than a competing one.
Which of the following, if true, would most strengthen the conclusion drawn above?
(A) It is possible to increase both the quality and the price of a product without changing its competitive position.
(B) For certain segments of the population of consumers, higher-priced brands of some product lines are preferred to the lower-priced brands.
(C) Competing products often try to appeal to different segments of the population of consumers.
(D) The competitive position of a product can be affected by such factors as advertising and brand loyalty.
(E) Consumers’ perceptions of the quality of a product are based on the actual quality of the product.

这个题目描述很微妙: 真实价值是由质量/价格的  即是一个比例,而不同的质量+价格组合最后比例可以相同.

比如2个产品  20/10=30/15   那么这个比例一样, 你凭什么说你处于竞争优势?  比例一样完全可以理解成竞争优势相同! 而题中最后一句是说通过提高质量压低价格来保持比例, 就是选择30/15 的组合  说这么做有优势.    

问题来了: 如果对手是采取20/10的组合呢? 比例也和你30/15一样!  题目说30/15的有优势哦~

看E: 消费者以质量为判断标准 30>20哦 如此, 即使比例一样也有优势!  加强了不是么!



老实打了一段话 可能说得有点复杂 希望大家仔细看~我觉得这题目应该是这意思


过两天考了...祈祷...

1.Teresa: Manned spaceflight does not have a future, since it cannot compete economically with other means of accomplishing the objectives of spaceflight.
Edward: No mode of human transportation has a better record of reliability: two accidents in twenty-five years. Thus manned spaceflight definitely has a positive future.
Which of the following is the best logical evaluation of Edward’s argument as a response to Teresa’s argument?
(A) It cites evidence that, if true, tends to disprove the evidence cited by Teresa in drawing her conclusion.
T没有引用任何evidence。
(B) It indicates a logical gap in the support that Teresa offers for her conclusion.
E没有就T从成本推导出论点的过程进行分析。
(C) It raises a consideration that outweighs the argument Teresa makes.
从对话中可以看出E的语气是比较弱的。如果把这两句话换换，T倒是很能outweigh E的观点。
(D) It does not meet Teresa’s point because it assumes that there is no serious impediment to transporting people into space, but this was the issue raised by Teresa.
正确。E直接跳过了T认为比较严重的问题开始憧憬美好的未来。
(E) It fails to respond to Teresa’s argument because it does not address the fundamental issue of whether space activities should have priority over other claims on the national budget.
fundamental issue不是航天事业拿不到钱，而是太花钱。

答案是D。为什么是D呢？

T：载人航天的成本过高，因此没有未来。
E：其实载人航天是迄今最安全的交通方式，因此它还是有价值的。

这个有点鸡对鸭讲的感觉。T又没说载人航天没有价值，只是成本太高而已。

这一题的C不对，是不是因为C中的outweight其实是做题人的主观判断了，而原文并没有证据可以证明这个outweight的判断呢？
