123. Advertisement: Today’s customers expect high quality. Every advance in the quality of manufactured products raises customer expectations. The company that is satisfied with the current quality of its products will soon find that its customers are not. At MegaCorp, meeting or exceeding customer expectations is our goal.

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

(A) MegaCorp’s competitors 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 of its customers is certain to fail in advancing the quality of its products.

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

(D) If a company becomes satisfied with the quality of its products, then the quality of its products is sure to decline. C

(E) MegaCorp’s customers are currently satisfied with the quality of its products.

答案是C， 想请问一下B为什么不对，原文说 advance in the quality =〉raises customer expectations  逆否命题不就是，can not customer expectations =〉fail in advancing the quality of its products 吗？正好是B啊。

LZ说的逆否命题是对的必然成立是对的, 但是, B选项不是原文的逆否

anticipate the expectations (company) 不等于 raise expectation (customer)

如果B选项是, can not raise expectation=>fail in advacing in the quality 才是原文的逆否命题.
