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

答案是(B)

請問這題第一句和第二句的關聯是什麼??
看起來只是一個在講oil一個在講gas!!
題目是問要如何支持!!
答案(B)怎麼個支持法??

麻煩哪位高手可以稍微花點時間詳細解說一下!!
真的是感激不盡!!
被這堤困擾很久了!!!

這應該是從文章中嘗試找出關聯性
第一句話說明冬天快來了,結果油價保持低價(已知,確定)
第二句話變成除非冬天很冷,不然天然氣也會保持低價(推論)
題目即考此兩句話中間補上什麼關係,可以強化作者做出第二句話的推論...
選項B說明oil與natural gas對消費者來說是替代品
因此以經濟學的觀念來看,如果天然氣的價格變貴,那麼消費者將會改用低價的oil
所以面對oil的競爭力,天然氣的價格將會跟著保持低價

我也來補充我的想法 :p
引用liwuu的翻譯:
第一句話說明冬天快來了,結果油價保持低價(已知,確定)
第二句話變成除非冬天很冷,不然天然氣也會保持低價(推論)
(第二句話就暗示: 天然氣的價格會受天氣的影響)

A 沒辦法說明油價與天然氣價格之間的關係
CDE 說明天然氣不太會受天氣影響(與第二句話的暗示矛盾)
B 大部份使用天然氣的人能以低價的油代替使用天然氣-->天然氣的需求下降
-->天然氣的價格下降

選項B能銜接第一句話與第二句話~
