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.
我选了B，求大牛解释E为何为正确？

The problem you posted was incomplete. Here is the WHOLE problem:

Because of the recent transformation of the market. Quore, Inc., must increase productivity, 10 percent over the course of 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.

有10% 就有 20%

逆否命题：没有20%，就没10%

所以选E

但是后面的20%的增长，没有给出是什么。前面的10%很确定是指产量。所以E选项很显然偷换了一个概念。

如果假定20%的增长指的也是产量的话，那这道题一点问题都没有。
因为原文可以做的推理只能够有以下几条：
1.如果在未来的2年中，产量没有增长，公司倒闭
2.如果产量增长10%，那么产量可以增长20%
如果假定推理1中要求的增长是10%的话，且对推理2取逆否命题就是：
如果产量没有增长20%，那么产量没有增长10%；如果在未来的两年中，产量没有增长10%，那么公司倒闭。
简化一下，就是，如果产量没有增长20%的话，公司倒闭。
也就是选项E

所以我觉得这道题里面有BUG，需要假定才能够完成全部的推理。
