I answered the questions as I knew they would be from where I was born and grew up -- but no longer speak that way.
For example, the carbonated beverage I called "pop" as a kid, but now I call "soda."
"Devil's Night" is the night before Halloween where mischief is played, windows are soaped and trees are TP'd, but there is no such "event" where I currently live.
So the end result is, the graphic shows that I grew up in the Detroit/Grand Rapids/Toledo area, which is true. But if I were to take the test based on the way I speak now, I would be curious how that would wind up.
