Is five something different here than in my timeline?I´m pretty sure that's five constructors, so what's the deal here. When i compared it to the given Solution it is pretty much the same too, just with some different calls to print the lines but results the same. Anyone got a clue?

Can someone explain what the question is asking? I think I am picturing the situation in this task incorrectly. The validator claims I'm wrong, and the other 2 people asking questions in the help section have answers that are not only completely different than mine, but I also can't make sense of them based on how I am picturing this in my mind.
