看看这道题, 答案是什么?

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.

因为B 是个必要条件。此题可以了解一下逻辑关系。题目说产量不增加一定破产,并没有证据说明增加就一定不破产。
