大全做的非常郁闷！

Ross: The profitability of Company X, restored to private ownership five years ago, is clear evidence that businesses will always fare better under private than under public ownership.

Julia: Wrong. A close look at the records shows that X has been profitable since the appointment of a first-class manager, which happened while X was still in the pubic sector.

Which of the following best describes the weak point in Ross’s claim on which Julia’s response focuses?

(A) The evidence Ross cites comes from only a single observed case, that of Company X.

(B) The profitability of Company X might be only temporary.

(C) Ross’s statement leaves open the possibility that the cause he cites came after the effect he attributes to it.

(D) No mention is made of companies that are partly government owned and partly privately owned.（C）

(E) No exact figures are given for the current profits of Company X.

前人的推理：

推理的过程是这样的，Ｒ　说　现象结果Ａ－－－＞原因Ｂ　即　赢利的能力有倒退到在私人所有权之下５年前的水平（暗示现在是公有）－－－－＞　原因是私有比工友好（因为赢利能力的不同）

Ｊ反对Ｒ，反对的方式是它因推Ａ．就是说不一定是Ｂ的原因．它因是ＦＩＲＳＴ　ＣＬＡＳＳ　经理的原因．（从而说明不是私有的问题．）

选项Ｃ说的就是这个意思｀！

我能理解以上的，但就是不知怎么和选项C联系起来，实在不好意思这么笨的问题？先谢了！

R: 因（私有化）----果（盈利）

J：先有果后又因（私有化前就盈利啦）----即答案C.即J指出的R的论证缺陷
