Since your obviously desperate to hear me answer these questions here ya go. In all honesty..
Colombus no clue
Emancipation no clue
pythagorean theory a2+b2=c2 used to find out lengths of sides of square triangles
I wasn't exactly sure what natural selection was except it was proposed by Darwin and had something to do with survival of the fittest
I didn't answer them all right, but I don't think that qualifies me as an idiot. There are more things to life than Q&A. Would you consider someone who loved life and made others around them happier and better people idiots even if they didn't know didly about common knowledge. Whatever, I'm not going to rant anymore on what the qualifications are for being an idiot.
