The root problem isn't something keen to fit in the guise of normal words. It's something that one could spend a very long time explaining without ever getting much across the void between two minds. It can be clearly defined and remain ambiguous. The root problem, to begin, is the question. The question as it is a whole concept, not a mere iteration of said concept. It is very important, however, to emphasize that the root problem is also the answer, particularly in the manner that it, the answer, becomes a question itself. Thus, the root problem is the question and the answer.
