大全-6-18，以前的讨论似乎都没到点上

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.

当时选A觉得就不对，也不是ETS的出题思路，但当时觉得E是个无关选项，消费者能了解产品的质量是这样买，不了解还是按照质量/价格的方法来买，觉得是个无关选项，大家有没有比较精确的思路

本题答案是E

原文有一个分式：产品竞争力=产品质量/产品价格

原文结论：把分母变大，或者把分子变小都能使产品竞争力增加

A）把分子和分母都变大可能使得运算结果增加=》无法加强原文

E）产品质量的提升能被消费者感知。

这说明“分母的变大导致运算结果变大”这件事情是能够被消费者认识到的，加强原文结论。

LZ可以反过来想一下，如果“分母的变大导致运算结果变大”这件事情消费者无法认识到的话，把分母变大就没有意义了。
