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.

但不明白怎样排除Ｂ，Ｃ．怎么都想不通．试着去apply 一些前面高手的经验和心得，还是不得其法．真是郁闷啊．真的很佩服那些视逻辑题如透明题的牛人们，真是不易达到的境界啊．

1。原文第一句话应该漏掉黑体部分Quore, Inc., must increase 10 percent productivity  the next two years

2。原文推理：donnot go bankrupt----->10 percent productivity increase (第一句话)------>a 20 percent increase (第二句话)

B。为逆命题。错

C。原文给的市场变化的信息是因果关系（BECAUSE OF），C选项是充分必要关系。因果关系推不出充分必要关系。错

E为逆否命题。对

Hi lawyer_1, 我对C,和E 现在理解了但对B 还是有疑惑.

我对原文的理解是:  QUORE must increase 10 percent productivity ( a 20 percent increase in attainable) the next two years, otherwise, it will go bankrupt.

所以我觉得B 的表达 :如果QUORE achieve productivity increase of 20%, it will Not go bankrupt 和原文不冲突啊. 我是不是那里理解错了?

同问！而且E中If a 20 percent productivity increase is unattainable for Quore，but 10% increase is possible ,it may not go bankrupt

这是MUST BE TRUE题，就是答案必须能从原文推出，即答案相对原文一定要真，要对。B是逆命题，就是可真，也可假。可对，也可错。所以不是答案。

10 or 20 percent of increase is the necessary condition for sucess in the recently transformed market.

Inc., must increase the next two years, or it will certainly go bankrupt

So, 必要条件， 无之必不然， 有之不必然。 B =有之必然，   （20 percent increase --> success)  错！

C,  充分条件， 有之必然， 无之未必不然。 C= 无之必不然。 （ no transform= no increase)   错！

为什么B是逆命题？ 不是否命题呢？很混乱啊。。。请教请教！！
