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.

以下是解析：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。

我不理解的是为什么10 percent productivity increase is possible和a 20 percent increase is attainable 对Quore, Inc来说才能算是increase， 为什么小于10%不可以呢？

同问同问，和LZ想法完全一致呀，但我想可能E是这五个选项中最靠谱的吧，其他的肯定不行，所以只能忽略那点“小毛病”吧！
