The Category Editor needs to message the writer to find places with no Grand Island to use for 'wrong' answers. That would be tough, since lots of research involved. Good lesson here - the Q&A's can't be local knowledge based; must be written to include the global community we have here.
Enough complaints and the quiz will segue into the 'limbo' queue. And I'm sure there are a great many states, provinces, territories and nations which have one, and from where complaints will come.
I'm fairly sure New Jersey doesn't have a 'Grand Island', if that's any help, but that's not 100% certain either.
