6.     Which of the following best completes the passage below?

Established companies concentrate on defending what they already have. Consequently, they tend not to be innovative themselves and tend to underestimate the effects of the innovations of others. The clearest example of this defensive strategy is the fact that______

(A) ballpoint pens and soft-tip markers have eliminated the traditional market for fountain pens, clearing the way for the marketing of fountain pens as luxury or prestige items

(B) a highly successful automobile was introduced by the same company that had earlier introduced a model that had been a dismal failure

(C) a once-successful manufacturer of slide rules reacted to the introduction of electronic calculators by trying to make better slide rules

(D) one of the first models of modern accounting machines, designed for use in the banking industry, was purchased by a public library as well as by banks（C）

(E) the inventor of a commonly used anesthetic did not intend the product to be used by dentists, who currently account for almost the entire market for that drug

题干讲的defending strategy，是说明这个strategy为反面教材，那么举的例子也应该是反面的阿。

我选的是A。但答案是C，C怎么看也不是defending strategy啊，明明为了improvement而引用了新技术。

请各位高手指教以下，感激不尽！

of course C is right, the fact that the slide rule manufacturer responded to the invention of calculator by improving their slide rules tells what the first part of the statement says, refuse innovation. Improvement is different from innovation.

其实有个偷懒的判别办法，因为是要提example，所以可以下意识的寻找一个有前面一部分提到的所有要素的答案：established company, innovation, that company's attitude (or response) to that innovation，其他四个答案要么引入了不相关的要素，要么不足，所以答案必定是C

感激不尽

原来我理解错C选项的意思了= =

豁然开朗阿
