In the past the country of Malvernia has relied heavily on imported oil. Malvernia recently implemented a program to convert heating systems from oil to natural gas. Malvernia currently produces more natural gas each year than it uses, and oil production in Malvernian oil fields is increasing at a steady pace. If these trends in fuel production and usage continue, therefore, Malvernian reliance on foreign sources for fuel is likely to decline soon.
Which of the following would it be most useful to establish in evaluating the argument?
(A) When, if ever, will production of oil in Malvernia outstrip production of natural gas?
(B) Is Malvernia among the countries that rely most on imported oil?
(C) What proportion of Malvernia's total energy needs is met by hydroelectric, solar, and nuclear power?
(D) Is the amount of oil used each year in Malvernia for generating electricity and fuel for transportation increasing?
(E) Have any existing oil-burning heating systems in Malvernia already been converted to natural- gas-burning heating systems?
题目分析：原文比较简单，说的是M这个国家开始把供热系统用天然气不用油，而且M天然气产量不错，油的产量也稳步增加，如果这个趋势持续，怎M就不再依赖进口油了。问评价，我们说过，支持驳斥都可以算评价，跑题不行，忠实叙述原文的也不行。A说油的产量超过天然气了，这个会评价M不再依赖进口油这个趋势吗？显然不会。杀B说M这个国家是不是严重依赖进口油的国家之一，这个和那个趋势也没什么关系，杀。C说M的energy有多少比例是有别的方式提供的（例如核能），我谈的就是油和天然气，没谈别的，跑题了，杀。D说是否别的地方用油的比例增加了，这个就会影响到我是否还会进口油这个趋势了，留着。E说现有的heating system是否能已经能转换成烧天然气的了，扯得比较远了，杀。
