OG-13-CR-72 用helr 的方案正在实践,遇到 不会的题 一枚。。
72. In the past thecountry of Malvernia has relied heavily on imported oil. Malvernia recently implemented a program to convert heating systemsfrom oil to natural gas. Malvernia currently produces more natural gas eachyear than it uses, and oil production in Malvernian oil fields is increasing ata steady pace. If these trends in fuel production and usage continue,therefore, Malvernian reliance on foreign sources for fuel is likely to declinesoon. Which of the following would it be most useful to establishin evaluating the argument? (A) When, if ever, will production of oil in Malverniaoutstrip production of natural gas? (B) Is Malvernia among the countries that rely most onimported oil? (C) What proportion of Malvernia’s total energy needs is metby hydroelectric, solar, and nuclear power? (D) Is the amount of oil used each year in Malvernia forgenerating electricity and fuel for transportation increasing? (E) Have any existing oil-burning heating systems in Malverniaalready been converted to natural-gas-burning heating systems? 因果推理 CON:M reliance decline p:M rely on import oil; program: convert system to gas; hasextra gas, oil increase
OA是D,我选的E
分析:现在貌似知道为啥不选 E 了,是不是因为如果不是方案推理,就不要质疑题目中给出的方案的可行性和有效性!!!E本来想的是质疑原文中提供的信息,这个转化是否能实现。做了这么多题发现质疑原文的信息一般都不能成为正确答案。只有在方案的时候,才质疑方案的可行性。这个不是方案推理,就不能够从那方面考虑。
但为啥选 D 呢,lz还是觉得D 不对啊。
oil= fuel….D中质疑了因果链,gas的产量大于消耗量;oil的产量现在小于消耗量,但是吧供热系统的本来用oil现在用 gas了,减小了oil消耗量,D中提出了其他系统的用oil量可能增加。即使加上了D的答案也不一定能能得到结论啊。因为你提出了这两个消耗oil的主要source,说不定还有其他的消耗途径啊。啊啊
任何地方分析的不对请指正啊啊啊
