How would I rate this picture?

When I changed the image over the short introduction on the right, I was directed to my Gravatar page. On this page you create the image and title with which you will be seen on the web, whenever you like, post or comment. This is the image that WordPress imports as your portrait, as seen on the right.
Above a screenshot of the little questionnaire I had to solve.

{I think I chose well, but what would the other images show?}
