Although, recent years have seen substantial reductions in noxious pollutants from individual motor vehicles, the number of such vehicles has been steadily increasing, consequently, more than 100 cities in the United States still have levels of carbon monoxide, particulate matter, and ozone (generated by photochemical reactions with hydrocarbons from vehicle exhaust) that exceed legally established limits.

D. have a larger and heavier fuel tank than a gasoline clonevehicle fueled with methanol

B 汽油车烧甲醇。

单纯比较效率 A > C > B 。但文章开头就说 A 引起环境问题,所以就算效率高,也不考虑了,这句话比较的是 B C,结论是 C 相对效率更高,更省油。

所以选 E
