请教一题扰人的逻辑，谢谢

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.

This is an inference question.

The easiest way solve this particular question is to use elimination.  You can quickly eliminate A, C, D, E because A, C, D, E are not supported by the question stem.  That left us with B.

To verify B, you can try "deny test".  Negate B, we get "Making the Russian ruble freely convertible to Western currencies will NOT cause the ruble’s value to decline".  This directly contradicts the stem, because if the opposite of B is true, government doesn't need to wait "until the question of ownership of state enterprises ... resolved" to make the ruble freely convertible.  Therefore, B is more likely an inference of the passage.

I have to admit that strictly speaking, the opposite of one statement contradicts the stem doesn't necessarily mean the statement itself is an inference of the stem.  But, for this particular question, it's the best way to attack -- as far as I can think of.

BTW, maybe you want to reformat your post to make it a little easier to read, so more folks may be willing to answer you?
