Adding an arrow pointing to it would make it much better. I like to miss when I don't know the answer, because at least I learn something from it. But there's no gain in missing because I can't find which item I should be looking for.
another one "close" is enschede
I think it should be more clearly indicated as finding the locations you're supposed to identify is not the point.
East Siberian Sea
East River (New York)
And I kind of was ecpecting east timor on this list!
((Also if you want to make this borderline impossible there is a state in brazil you could add called Espirito Santo
