I have no idea how to google this.
Basically my question is: is it plausible that a poorly educated American teenager would not know when Columbus first landed in America?
I know I had to look it up as a relatively well educated British person with little interest in history. I am wonderinhg though if in the states it is so mmuch common knowledge like for example the dates of the world wars that not knowing would seem strange.
Some background, my characters are having a conversation about wide ranging topics and it comes out that one of them doesn't know which century it was. The character is 19 fairly bright but had a pretty spotty education, poor attendence and changed schools a lot.
I had to look it up (US history was barely touched upon when I was at school) it didn't occur to me till later that his not knowing might be unlikely for a US citizen.
