问题 This passage gives a general description of the advantages and disadvantages of a hybrid auto- mobile.
The series hybrid vehicle is sometimes directly powered by the gasoline engine.
选项 A、Y
B、N
C、NG
答案B
解析 Hybrid Structure部分第二段最后一句为答案出处，文中先对混合动力汽车中柴油发动机的工作原理进行了描述，最后得出结论：Thus，the gasoline engine never directly powers the vehicle，即柴油发动机从不直接驱动混合动力汽车。题干中的sometimes和原文中的never相悖，因此错误。
