i am pretty sure that a system in general is whatever you define it to be. i would say that all of them are systems.

No. The question came from a class, right? And this class is studying the properties of systems, correct? What is the definition from the textbook for this class of what a system it? If it's an economics class, there will be one definition. If it's a physics class, the definition will be different (and very specific).
