问题 Maglev trains are comparable to airplanes in revolutionizing the transportation.
The engine for maglev trains is used to pull train cars along steel tracks.
选项 A、Y
B、N
C、NG
答案B
解析 第1个小标题Electromagnetic Suspension (EMS)部分的第3段第1句：The big difference between a maglev train and a conventional train is that maglev trains do not have an engine—at least not the kind of engine used to pull typical train cars along steel tracks．原文中破折号后对the kind of engine的描述指的是conventional train的引擎，而题目把它张冠李戴为磁悬浮列车的引擎，故答案为N。
