Hi petrophysics1
I didn't mean to criticize the whole test, it was quite interesting.
However, asking such a question about Leonardo really is not really important.
I also found some questions and answers 'a bit ambigeous and/or I take issue with the correct answer' (as a previous poster said).
I would love to read that article on Leonardo, but you didn't include the link.
You'll never change Faith's mind, no matter how much evidence is show, she'll always ignore everything she doesn't want to hear. It's more for the lurkers who only hear the creationist untruths to start thinking about what actually has been discovered in real life.
