I'm not clear what you are saying. I am curious about what humans can do in the same context. It's becoming a standard I think for some tasks. E.g. how does a Gen AI stack up against a human in quality and "cost". Perhaps I'm missing what you are asking.

They can. Ask them to generate SVG , call a renderer and let them inspect the bitmap/png. They can learn about it.

They can, but for this specifc test, they don't. It's a oneshot with no feedback.
