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）

(E) Consumers’ perceptions of the quality of a product are based on the actual quality of the product.

the answer is E

what's the wrong with A?

I think A is much better

怎么没有人回答

是这么想的。

题目说value=quality/price,而value决定了competitive positon,因此，竞争地位就由质量比价格决定。

选项A,说当可以通过同时提高quality和price而保持竞争地位不变。我觉得没问题啊，同时提高分子和分母，分数值不变

请问这样考虑的错误在哪里，谢谢了

嗯，又看了一遍题，好像是理解的有问题。

针对题目的结论来说，只是问怎样支持“提高质量和降低价格会增强竞争地位”

谢谢。

谈谈我对这道题的看法，我和搂主一样也选了A，而这道题问的是加强，所以不能用文中的信息来推倒A，而是要看由A推倒的结论是否对原文加强，如前人所讲， A有可能推出与原文矛盾的结论，所以不可能是加强。而E则通过排除消费者认为质量随价格变化的可能而对原文进行了加强。

P.S：如果这道题是演绎题的话，A是否就可看作正确答案了呢？

还请大牛确认！

如果没有if possible，a是答案。
