【OG24-778题】Delta Products Inc. has recently switched at least partly from older technologies using fossil fuels to new technologies powered by electricity. The question has been raised whether it can be concluded that for a given level of output Delta's operation now causes less fossil fuel to be consumed than it did formerly. The answer, clearly, is yes, since the amount of fossil fuel used to generate the electricity needed to power the new technologies is less than the amount needed to power the older technologies, provided level of output is held constant.In the argument given, the two boldfaced portions play which of the following roles? _mofa留学圈mofaGRE在线题库系统_GRE在线搜题_GRE题库解析_GRE真题机经_GRE课程_GRE培训机构

由电力驱动的技术。有人提出这样一个问题：对于给定的产量水平，Delta现在的运营是否比以前消耗更少的化石燃料。答案显然是肯定的，因为在产量水平保持不变的情况下，为驱动新技术所需发电的化石燃料量少于驱动旧技术所需的量。 逻辑链
New tech < Old tech (fuel) → Less fuel now 问题类型
句子作用题 推理过程
论点是对于给定产量水平，Delta现在运营消耗化石燃料比以前少。第一个加粗部分是在阐述为新技术发电所需化石燃料少于旧技术，这是支持论点的依据；第二个加粗部分“答案显然是肯定的”明确了论点内容。 选项分析
A选项：第一个确定论点内容，第二个支持论点，顺序错误，排除。 B选项：第一个支持论点，第二个确定论点内容，符合推理，正确。 C选项：第二个没有质疑结论，排除。 D选项：第二个没有质疑结论，排除。 E选项：第一个是支持结论，第二个不是支持结论，是结论本身，排除。
