1. There's always one answer to a question
Throughout the process of partaking in systematized educational institutions, there's always a criterion that applies to all the taught knowledge - That there's an answer and it is absolute. Math shares the strongest characteristic of ability to freely choose how one goes about to arrive at the answer. Grammar rules have exceptions, but exceptions are also a form of indisputable truth. This does not mean that the questions, answers and methodologies change. They change to new answers that once again follow the criterion. Granted, they also change at a futilely slow rate.
More importantly, the education would contain questions that are without definite, objectively true answers, but several different ones that make sense depending on the student's subjective perspective. Why is this of importance? The students get programmed that these questions are irrelevant since they are not spoken of. Accordingly, they have trouble living a life guided by personal values, ethics and patterns that correlate with each person's own, innate orientation. The challenge is simply to allow and present more answers to young aspirants of life so that they know of more answers to choose from, that they previously did not know existed. Therefore, it may sometimes be far more important to question where an answer derives from, instead of how to reach it.
