Oh, dear.
Not the sharpest knife in the drawer....
Well duh!
She gets my vote...
I think the whole thing reflects badly on the US education system. To have so many people unable to point out their own country on a map is almost unbelievable.
As for Miss Teen South Carolina, I think you should seriously think about having her locked away somewhere - anyone that dumb isn't going to be able to survive in the world anyway.
Back when I was at school (UK), between the ages of 9-11, as well as the usual memorising of multiplication tables, we had to learn the capital cities of countries. If you didn't get them right, you didn't go home, simple as that. Another was being able to name and locate seas and oceans.
Later, we would have to learn all UK counties and capitals. Also French Regions and US States. In secondary school geography was a compulsory subject. So you had to learn which countries things like coffee and rubber came from, also what the process was and learn about the social structure of the country.
Of course, that was a long time ago, I have no idea what is being taught today
