我不觉得E是对的（附CD的解释）。这里的20%是如何成为条件的一部分的？？

107. Because of the recent transformation of the market, Quore, Inc., must increase the next two years, or it will certainly go bankrupt. In fact, however, Quore’s production structure is such that if a 10 percent productivity increase is possible, then a 20 percent increase is attainable.

If the statements above are true, which one of the following must on the basis of them also be true?

>>

A.        It is only Quore’s production structure that makes it possible for Quore to survive the transformation of the market.

B.        Quore will not go bankrupt if it achieves a productivity increase of 20 percent over the next two years.

C.        If the market had not been transformed, Quore would have required no productivity increase in order to avoid bankruptcy.

D.       Because of the transformation of the market, Quore will achieve a productivity increase of 10 percent over the next two years.

E.        If a 20 percent productivity increase is unattainable for Quore, then it must go bankrupt.

【正确答案】E>>

【解题思路】>>

本题的类型是归纳类，即如果原文正确，可以得出什么结论或推出什么。

可简化题干的表述为：

transformation of the market（A）→Q increase its production（B）

Q not increase its production（非B）→Q will go bankrupt（C）

选项A的表述为：Q’s production structure→Q will not go bankrupt（非C），无法从题干中推出。

选项B的表述为：Q increase production（B）→Q will not go bankrupt（非C），为的逆命题， 不成立（原命题与其逆否命题等价）。

选项C的表述为：market had not been transformed（非A）→Q will not need to increase its production（非B），为的逆命题， 不成立（原命题与其逆否命题等价）。

选项D的表述为：transformation of the market（A）→Q will achieve a productivity increase，无法从题干中推出。

选项E的表述为：Q not increase production（非B）→Q will go bankrupt（C），与一致。

已经讨论过的很多帖子是个宝库，请大家珍惜，研究。这样问，效果并不一定比搜索阅读前人的来好。最早的那些大牛都归隐了啊，只剩下这些帖子了。
