I'm not sure it does. I did ask 5 adults this question, with zero context about what we're discussing with AI, just posing it as a riddle. They were split, with lots of uncertainty about the optics of the glass straight on, and where the viewer is vertically with respect the glass' height. The best response, from my wife, brought up the trig aspect to the problem, pointing out that nothing in the question talks about distance to or between the objects. Her assumption was that the peanut could easily be offset behind the glass from her perspective, resulting in the peanut not being visible.
We tried the experiment, and she was right that there are definitely setups of distance and spacing that cause the peanut to not be visible. Try it!
