20.   Despite the approach of winter, oil prices to industrial customers are exceptionally low this year and likely to remain so. Therefore, unless the winter is especially severe, the price of natural gas to industrial customers is also likely to remain low.

Which of the following, if true, provides the most support for the conclusion above?


(A) Long-term weather forecasts predict a mild winter.


(B) The industrial users who consume most natural gas can quickly and cheaply switch to using oil instead.


(C) The largest sources of supply for both oil and natural gas are in subtropical regions unlikely to be affected by winter weather.


(D) The fuel requirements of industrial users of natural gas are not seriously affected by the weather.（B）



(E) Oil distribution is more likely to be affected by severe winter weather than is the distribution of natural gas.



B怎么支持的啊，如果B支持，C 不就更支持了，方向在哪里呢？

如果油和气之间的价格上的关联关系建立了，则气的价格必然受油的价格影

响，只要油很便宜，如果气涨价，就用油了。

c的错误在于其陈述的事实和问话没有关系。

不要着急，这说明你正处在把你自己的思维往ETS的思维靠的过程中，这是一个平台期，你要度过了这个平台期，水平就能上一台阶，到时候看什么都很清晰了。同样，你要是度不过这个平台期，就怎么也上不去了哦。所以现在要耐心多读多看多总结，很快会培养起固定思维的：）加油。

看了这贴，我对这个问题也有了些感觉，我想补充一下我的想法：Therefore, unless the winter is especially severe, the price of natural gas to industrial customers is also likely to remain low. 就是说只有在winter is not especially severe的情况下，天然气的价格才会remain low。反之，winter is severe导致天然气价格上涨，但此时人们都改用了oil，用oil比用天然气更经济实惠（cheaply），而且还不费事（quickly）

I feel answer B is not very good, although there may not be a better answer.

If nature gas is expensive, industrial users will switch to oil. This is fine. However, this does not say nature gas price will remain low. It can still be expensive, but not many people using it.

Gold is expensive. So many people use silver to decorate. But gold is still expensive than silver.

This answer is not a typical ETS style. Just my opinion.

B does require the assumption that when demand decreases, the price will decrease accordingly. However, the question is asking for “the most support”. In another word, you should choose the best answer, not the perfect answer. This question epitomize the style of GMAT CR.
