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.

我在B和E中搞，个人选的是B，但答案是E。

我的思路是：B：如果这公司生产率增加20%， 那就是增加了，就不会倒闭了。 满对的样子嘛

                    E： 如果这公司生产率20% unattainable，那么就是10% impossible,  我觉得就算没10%么，如果增加在0~10%之间，那也算增加呀！ 那只要增加么，厂就不会倒闭了嘛？？！

题目中没说增加20%会不倒闭  增加会不倒闭 但没说要增加多少才不倒闭  你给出20% 推理过激了

既然他没说要增加多少才不倒闭，那为什么说“如果它的增加不到20%，就肯定倒闭”是MUST BE TRUE的呢？？

这条E选项是不一定啊，所以我觉得是COULD BE TRUE， 不是MUST BE TRUE啊

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。
