Sorry, I was describing the visual images I get when solving problems like this, the article is pure text.

Hmmm. Interesting that you point that out. I think if we were presented with a math formula (symbols), we'd have aced it.

I think the reason why my wife did it so fast is because it was fed to her as text only - in fact, I just read it to her. She's a lawyer and she's much better at interpreting text than most people.
