The quiz is pretty bad. #1; the year-olds know V=5 and X=10 2. your #2 is incorrect as there were submarines in Ancient Rome and Greece, and USA high school teens are taught of the subs used during Civil war . . . . . I will only go as far as #3 as 90% of Americans have no idea (nor do they care) for #3 and it is based on a bias of geography; do you think anyone in Europe can name the State Capitol of Kentucky ??? Can you ????Which MLB teams play on Ohio ??? did not even bother. Just for your info, this is based on my knowledge of gen info on college tests as a narrator and judge in Quiz Bowl.
