First, the question of existence, does X exist, or not? Second, depending on the nature of the item in question, could be along the lines of does it have matter or do I, as a human, have the ability to recognize it? Contemplate this a while.
Once you get passed the existentialism, you get to questions more related to ability and function. For example, can a human eat a chicken? Can I walk 500 miles?
Once what can and cannot be done has been determined and completely explored, the questions become a matter of choosing to commit an action or not. Every single particle in the universe can participate and be examined using these yes/no questions until the question of choices arise. At that point, in my opinion, only animate beings can participate and at varying degrees depending on various elements such as instincts. But humans, when faced with a problem or dilemma often throw in questions of morality or righteousness before inquiring about willingness.
Either way, almost anything can be “figured out” with yes/no questions. But when grappling with those difficult decisions, a choice is always made, yes, or no. As humans, I think we all try to consistently pick the best one, even if it seems like a bad one.
