Siduria recently implemented a program to convert heating systems from oil to natural gas. Siduria already produces more natural gas each year than it burns, and oil production in Sidurian oil fields is increasing at a steady pace. If these trends in fuel production and usage continue, therefore, Sidurian reliance on foreign sources for fuel should decline soon. Which of the following is an assumption on which the argument depends? A.In Siduria the rate of fuel consumption is rising no more quickly than the rate of fuel production. B.Domestic production of natural gas is rising faster than is domestic production of oil in Siduria. C.No fuel other than natural gas is expected to be used as a replacement for oil in Siduria. D.Buildings cannot be heated by solar energy rather than by oil or natural gas. E.All new homes that are being built will have natural-gas-burning heating systems.
这题目选A，我想请问一下，读题目的时候，题目前面说了一大段：In the past the country of Siduria has relied heavily on imported oil. Siduria recently implemented a program to convert heating systems from oil to natural gas. 之类的话，这些对做题有帮助吗？感觉选项A只说了题目中众多个概念中的两个？.........而且概念一多，人就有点混乱了，要如何应对这类题目呢？~
