Where is the real and unambiguous solution?

 

I have been looking for an answer for a long time. What I have discovered, I present to you here

Is there any clear reply to this question at all?

Or maybe there are even many correct positionings? How important is it to know the only correct answer?

The search for feedback has occupied me so intensively for quite a while that I was in danger of losing sight of my own ideas.
