为什么答案B的ruble values不是上升？

(B) Making the Russian ruble freely convertible opt Western currencies will cause the ruble’s value to decline.

Privatization of the large state enterprises that comprise the industrial sector in Russia is proceeding slowly, due to competing claims of ownership by various groups. Continued government subsidization of these enterprises creates large deficits that drive up the inflation rate and cause the ruble’s values to decline. It is therefore unlikely that the government will make the ruble freely convertible to Western currencies until the question of ownership of state enterprises has been resolved.
If the author’s prediction concerning the ruble is accurate, which one of the following conclusions can most reliable be drawn?

(A) The industrial sector accounts for at least fifty percent of Russia’s economic activity.
(B) Making the Russian ruble freely convertible opt Western currencies will cause the ruble’s value to decline.
(C) The Russian government can indefinitely withstand the expense of subsidizing state enterprises.
(D) The Russian government is among the groups claiming ownership of certain state enterprises.
(E) The Russian government is under pressure from the West to make the ruble freely convertible to Western currencies.

Ans: B

这是一个归纳题：

利用公共原素排除法：

1.私有化的问题导致卢布贬值。

2.直到私有化的问题解决了，（即卢布不贬值），才允许货币自由兑换。It is therefore unlikely that the government will make the ruble freely convertible to Western currencies until the question of ownership of state enterprises has been resolved

说明卢布不贬值和货币自由兑换是不同的两个阶段。

我也不确定是否可以看成：A until B       可得    B-->非A

请nn指点

感谢你的解释，不过我有个小疑惑，请问题目的意思是说私有化的问题导致卢布贬值吗？题目说Privatization of the large state enterprises that comprise the industrial sector in Russia is proceeding slowly, due to competing claims of ownership by various groups. 因为很多团体相互竞争都想拿到政府事业经营权，因此Russia 政府事业私有化的进行的很慢Continued government subsidization of these enterprises creates large deficits that drive up the inflation rate and cause the ruble’s values to decline. 我的理解是国有化导致卢布贬值，It is therefore unlikely that the government will make the ruble freely convertible to Western currencies until the question of ownership of state enterprises has been resolved.直到确定哪一个团体得到经营权后，才允许货币自由兑换。

但是我的理解得不到 (B)政府让货币自由兑换卢布会下降。

请各位解释看看，感谢

1。make the ruble freely convertible to Western currencies推出the question of ownership of state enterprises has been resolved（直接来源原文）

2。the question of ownership of state enterprises has been resolved推出Continued government subsidization of these enterprises （对原文的理解）

3。Continued government subsidization of these enterprises 推出  the ruble’s values to decline（直接来源原文）

1推2推3，便得B。其它选项不可能对。

dreamer710821，我觉得你是想的太多，做归纳题，就是看文中有没有出现过。lawyergg已经分析的很好了。

我说的是私有化的问题：就是私有化问题解决不好，就需要政府资助，这样卢布就贬值。而不是说私有化导致贬值，事实上根据原文，私有化完成的化，卢布就升值了。

你在理解试试。

这是根据公共元素直推法推的，就是把相同部分去掉，得出结论。
