You should understand that this is not a homework service nor is it a tutorial service.
PLease either post some of your own work on this problem or explain what you do not understand about the question.

There's nothing I don't understand about the question. I'm just having difficulty thinking up possible examples. I'm not asking for answers, but a point in the right direction.
