愁～～再问大全11－20！！！

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

答案是B。 偶看了前面的帖子，可是还不是很明白。这里的conclusion是说冬天来了，oil price会很低，而gas price在天气不是很严重的时候也会很低，是吗？B说了用oil 和gas 的关系，可是还是看不出来和题目问的结论有什么关系？偶知道oil 和gas之间是少了一段桥，可是就是理不清，不知道怎么搭啊！！急死偶了！！
