(第二种题型:多项选择题II)



Sample Multiple-choice Questions — Select One or More Answer Choices


Consider each of the three choices separately and select all that apply.
2.  The passage suggests that extensive use of sequestration would, over time, have which of the following consequences?
A.     The burning of fossil fuels would eventually cease to produce atmospheric accumulations of carbon dioxide.
B.     The proportion of the delivered price of electricity due to generation would rise and then decline.
C.    Power plants would consume progressively lower quantities of fossil fuels.

Answer: B

解析:首先,从文章中可以看出,没有什么方法可以“停止”大气中二氧化碳的累积,所以A选项中所提到的“The burning of fossil fuels would eventually cease to produce atmospheric accumulations of carbon dioxide.”显然是错误的。另外,整个文章中也并没有提供一种方法可以使得电厂可以 “减少化石燃料的使用量”,所以C选项显然不符合题意。由于文章中的最后二句话中指出:“But because sequestration does not affect the cost of electricity transmission and distribution, delivered prices will rise less, by no more than 50 percent. Research into better technologies for capturing carbon dioxide will undoubtedly lead to lowered costs.”所以,随着化石燃料使用量的增加,未来可以预期的发电成本将会先增加后减少。应该选择选项B(The proportion of the delivered price of electricity due to generation would rise and then decline.)由此可以看出,尽管新GRE考试中出现了新的多项选择题型,但是并没有在实质上改变原有的命题核心思想。即考察考生的对文章事实的理解和推断进一步信息的能力。所以,原有的解题方法的运用不仅是可能的,也是必要的应对新GRE考试的工具。
