I have lived in New England my whole life, and I have never heard of Hartford as the "so-called insurance Capital of the World"! That was a total guess.
Interesting to see Topeka last and not completely surprising. I am, of course, familiar with Brown vs. Board of Education. But one is tempted to think it happened in Arkansas (think the Little Rock Nine) or Alabama (think the infamous image of George Wallace standing in the schoolhouse doorway). Remembering that it was Kansas serves as a reminder of just what a wide-spread problem segregation was and is.
We may have come a long way to integration, but it's interesting to note that a significant number - i.e. most - neighborhoods in the US are still mono-racial.
Perhaps the point of the quiz is just about naming capitals, but if not, would a yellow box be good here?
