NEW TPO 8 Which of the following does the passage suggest about the use of MFCs in wastewater treatment?

该题为推理题，题目：关于MFC（微生物燃料电池）在污水处理中的应用，以下哪项是文章暗示的？ 解题思路：需要仔细阅读原文中提及了“MFCs”和“wastewater treatment”的地方，推理出答案。 直接定位原文第三段第一句：“One of the most promising applications of MFCs is in wastewater treatment.”从这里开始，整个第三段都在介绍MFCs在污水处理中的应用。 选项分析： A.It has only been successful in smaller wastewater treatment facilities.（只在小型污水处理设施中取得成功）原文未提及大型污水处理设施和小型污水处理设施，属于无中生有，排除 B.It does not clean water as well as traditional methods of treating wastewater do.（净水效果不如传统方法）原文第二句话“Traditional methods of treating wastewater are energy-intensive, but MFCs can treat wastewater while simultaneously generating electricity.（传统污水处理方法需要消耗大量能源，而MFC既能处理污水，又能同时发电。）”这里只对比了“energy use”，没有比较清洁效率，排除。 C.It is more sustainable than other types of wastewater treatment.（MFC比传统污水处理方式更具有可持续性。）直接定位原文第三句话：“This dual function makes them an attractive option for sustainable waste management.（这种双重功能使其成为一种有吸引力的可持续废物管理方案。）”符合原文，正确。 D.It requires a large investment in new infrastructure.（需要大量基础设施投资。）原文未提及投资，无中生有，排除。
