#10 Wrong. Comes from the Latin word Schola wich means, well, school.

Latin "schola"
Etymology: from Ancient Greek "σχολή" (skholḗ).

They also invented the famous greek yogurt.

some things should never change like #14

The Greeks had many brilliant innovations in philosophy, mathematics, astrology, medicine, political theory, the arts and much, much more. The reason behind this is that they had nothing but free time because the slaves were doing all the work. I'm not advocating it, but if not for slavery...

#9 It's a little more complicated than that, but basically true. The word "idiot" referred to a "private citizen", as opposed to someone who held a "public" office. It did not mean "stupid."

#7 no sh#t Sherlock

#4 that's a pretty wide range estimate. A 40% margin for error is not good. It makes me think they don't actually know.
