come on, that's totally different, many of them get the questions right, the questions are more difficult, and when they're wrong they are usually making at least somewhat rational guesses. There are a few examples of dumb responses, but to not know who was the first president to live in the white house or to think Virginia was the first US state isn't embarrassing. The kids in the other video literally could not do basic arithmetic and were guessing "Africa" was a border country? Like I said, I could figure ways to allow for certain things - vocabulary changes, some history may be specialized - but some knowledge should be pretty standard.
