If you don't understand the assignment, you really need to ask the instructor. I think your instructor may mean "use many linked lists."
Multiple linked lists is a new one on me, I do not know what to implement off the bat, though I have a couple more ideas. So I think your instructor wants many different lists. You can ask him to explain what he means. If you do not have time for that, it's best to try to figure out the rest of the assignment, and do it the best you can. Then when you hand it in you can explain that you did not understand what he meant.
