问题 Maglev trains are comparable to airplanes in revolutionizing the transportation.
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。
