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.
正选为E，为为什么？题目不是说商家致力于提高产品性价比来吸引顾客吗？为什么E能加强？作者: painsper 时间: 2010-6-4 22:27
(A) It is possible to increase both the quality and the price of a product without changing its competitive position.
这个选项说产品的竞争地位有可能不会变如果同时提升产品的质量和价格，和题目的意思有些接近，但是这只是一个可能性，如果题目是让我们infer的话我想他应该就是正确的了，但是不能加强题目的结论
(B) For certain segments of the population of consumers, higher-priced brands of some product lines are preferred to the lower-priced brands.
这个选项说某个阶层的消费者，更喜欢高价位的某些产品，没有关于性价比的信息，无关选项
(C) Competing products often try to appeal to different segments of the population of consumers.
这个选项说竞争产品经常会去吸引不同的客户群，没有关于相加比的内容，无关
(D) The competitive position of a product can be affected by such factors as advertising and brand loyalty.
说产品的竞争力收广告和品牌影响，文中没有，排除掉
(E) Consumers’ perceptions of the quality of a product are based on the actual quality of the product.
排除了上面四个，只能剩下这个正确了，说消费者的质量观念不是建立在真正的产品质量上的，这样就可以合理推出即时产品质量不好，价格合理的话，消费者也会买，也就是说消费者并不一定就是要买质量好的产品的，质量相对差的也会买，所有可以加强作者: shaoyipeng 时间: 2010-6-5 07:49
假如生育率低归罪于T的话，那么跟犀牛有没有collar就没有关系了。我的例子中这种情况因为50只犀牛打的T都一样，那么结论就应该是大家的生育率是一样的低，而不是Female rhinoceroses that have been frequently recollared have significantly lower fertility rates than uncollared females。因此从这一点证明了Collar的犀牛不是因为打了T而导致比其他没有Collar的犀牛生育率要低。
