问题 Maglev trains are comparable to airplanes in revolutionizing the transportation. [br] Japanese maglev trains are different from German ones primarily in ______.

选项

答案 electromagnets

解析 第2个小标题Electrodynamic Suspension(EDS)部分的第1段第2句:The key difference between Japanese and German maglev trains is that the Japanese trains use super-cooled,superconducting electromagnets.空白处需要名词性成分。根据原文,德、日磁悬浮列车最关键的不同在于日本的磁悬浮列车使用了super-cooled, superconducting electromagnets,也就是说,德国的磁悬浮列车也用了electromagnets,但并不是日本的那一种。而题目考查的是在什么方面不同,故答案为electromagnets。
