Proposal: Carbon dioxide and methane in the atmosphereblock the escape of heat into space. Soemission of these “greenhouse” gases contributes to global warming. In order to reduce global warming, emissionof greenhouse gases needs to be reduced. Therefore, the methane now emitted from openlandfills should instead be burned to produce electricity. Objection: The burning of methane generates carbondioxide that is released into the atmosphere. Which ofthe following, if true, most adequately counters the objection made to theproposal? A. Every time a human being or other mammalexhales, there is some carbon dioxide released into the air. B. The conversion of methane to electricitywould occur at a considerable distance from the landfills. C. The methane that is used to generateelectricity would generally be used as a substitute for a fuel that does notproduce any greenhouse gases when burned. D. Methane in the atmosphere is more effectivein blocking the escape of heat from the Earth than is carbon dioxide. E. The amount of methane emitted from thelandfills could be reduced if the materials whose decomposition producesmethane were not discarded, but recycled. 这道题我读明白了而且选项也读明白了,只是对标红的部分不理解,它问的是以下哪个选项可以反驳这个反对者?还是以下哪个选项可以用来反驳这个提案? 因为答案选的是D,D不就是说甲烷比二氧化碳更能有效的抑制地面热量的扩散吗,这样的话不就是支持这个提案了,所以我怀疑是不是我没有理解对这道题
谢谢解答
