Subject: Can you help?            

From: Rose

Dear Knowledgeable,

    I have a good friend, Ann. She is very clever and can speak English really well. A very important English speech contest for our whole city will be held next month. Our classmates all think Ann is the best person to represent the class in the school contest and make sure she will win. But the problem is that she's very shy and that she's terrified of speaking in front of other people.

    She can't tell others about it, because she doesn't want to let her friends down. I can't think of any good advice to give her, but you always come up with good solutions to people's problems. Can you give us some good advice？Do you think we can tell the truth to the rest of the students?

Yours,

Rose

如图所示，折成不同形状的四个导线框质量相等、匝数相同，高度相同，MN边长度相等，将它们用相同的细线悬挂在空中，四个导线框的下边处在同一水平线上，且四个线框的下半部分都处在与线框平面垂直的同一匀强磁场中，磁场的上边界水平（如图中虚线所示），四个导线框中都通有顺时针方向、电流强度相同的电流，均处于平衡状态．若使磁场缓慢变强，细线最不易拉断的是（   ）
