问题 Maglev trains are comparable to airplanes in revolutionizing the transportation. [br] Electromagnets are not exactly the same as other magnets because the magnetic pull of electromagnets is not permanent.
选项 A、Y
B、N
C、NG
答案 A
解析 第1个小标题Electromagnetic Suspension(EMS)部分的第l段第3句：Electromagnets are similar to other magnets in that they attract metal objects，but the magnetic pull is temporary．题目和原文均为对electromagnets和other magnets的比较，题目中的not permanent与文中的temporary意思一致，故答案为Y。
