OG12 CR 33关于充分，必要条件的运用

有理想没有钱

33.Advertisement: [c1] Today’s customers expect high quality. Every advancein the quality of manufactured products raises customer expectations.[c2] The company that is satisfied with the current quality of its productswill soon find that its customers are not. At MegaCorp, meeting or exceedingcustomer expectations is our goal.

Which of the following must be true on the basis of the statements in theadvertisement above?

(A) MegaCorp’s competitors[c3] will succeed in attracting customers only if those competitors

adopt MegaCorp’s goal as their own.

(B) A company that does not correctly anticipate the expectations [c4] of its customers is certain to fail in advancing the quality of itsproducts.

(C) MegaCorp’s goal is possible to meet only if continuing advances in product qualityare

possible. C[c5]

(D) If a company becomes satisfied with the quality of its products, thenthe quality of its products is sure to decline.[c6]

(E) MegaCorp’s customers are currently satisfie[c7] d with the quality of its products.

这题的逻辑链条是，质量上升A那么就能提高用户的期望B，满足以及超过用户期望就能达到公司的GOAL(C).
答案是C, 仅仅只有质量上升才能使得公司能达到自己的GOAL.  这个仅仅让我很郁闷，ONLY IF 一般是说必要条件，而题目里面A到B到C都是一路充分过来，这里面有GAP，所以我觉得答案B貌似差点啥东西，请好心人帮我指导下，谢谢。。。。

B is wrong because the words "is certain to fail." Nothing in the world is certain except tax and death! Even in the GMAT world. A company may not correctly anticipate the expactation of its customers.  However, the same company can still advance the quality of its product. Just in a different way from that of the expectation.

Assumption question is a type of must-be-true question. In this case,  which is a must be true question, the must be true part is the assumption made by the author - continuing advances in product quality are possible  - to reach his main conclusion: The company can meet its goal.
