I was kind of debating between A and E, can anyone let me know why one should be preferred than the other one?

The value of a product is determined by the ratio of it's quality to its price. The higher 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 bothe the quality and the price of a product without changing is competitive posistion

B)For cerain segments of the population of consumers, hightr-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's perceptions of the quality of a product are based on the actual quality of the product

A:  Value=(Quality / price) : Quality up; price up  value might still be the same means competitive position unchanged.

E: if NOT E, then, competitive position is uncertain.?

confusing...

MM, confusion about the passage or my question:

my question is: I found A and E both correct in certain way as follows:

A is right in that--- Value=(Quality / price) : Quality up; price up  value might still be the same means competitive position unchanged.

E is right in that--- if NOT E, then, competitive position is uncertain.

So which one should we choose from A and E

我觉得应该选择E.

A) it is possible to increase bothe the quality and the price of a product without changing is competitive posistion 基本上是题干中The value of a product is determined by the ratio of it's quality to its price. The higher value of a product, the better will be its competitive position. 的重写。但是，它没有任何加强题干的意思（用的是possible ，即使是must be 应该也不是加强，因为这是题干推出的必然结论）。

而E相当于说消费者领悟的是产品的实际价值，如果你增加了价值（因为消费者是感觉得到的）而价格不变，或者价值不变而价格降低，都会增加消费者选择本产品而不是竞争对手的产品的可能。

Thank y H GG:

"即使是must be 应该也不是加强，因为这是题干推出的必然结论" makes it very clear to me now, if the question is ask about the inference from original passage then A might be right, however, as you just said, the question is about Strongen, so E will is preferred.

Thank y

B GG's analysis is right, Customer's perceptions of question sure bridge up the "quality " of a product thus further impact the value-that is the competition position
