Some of the questions have more to do with following the news than learning science fundamentals.
For example, the classification of pluto, the nature of stem cells, the discovery of water on mars.
Still, it's pretty sad how low some of those scores are.
Only 33% of high school graduates knew that electrons are smaller than atoms !?!?!

You probably shouldn't be shot....
It's a pretty poor representation of scientific questioning, and as pointed out is more worthy of news items than scientific know how.
However, I would have thought that everybody should know an electron is part of an atom, in today's world - literally.

If you don't get 12 out of 12, and score more than 90%, as 10% of the US population did - you deserve shooting! 🙂

Question 7, AFAICT, is wrong as well: they've discovered evidence of the existence of water in the (astronomically) recent past, but not actual water currently present.

BTW the answer about GPS is satellites but that is not the right answer, the right answer is very accurately timed radio waves using relativity equations to account for the movement and various gravity field strengths the satellites encounter. The satellites are just the boxes housing the equipment to do that job.
I thought the ice at the pole are actually frozen carbon dioxide.
