For some reason, at some point during this quiz my mind thought the answers had to be 3-letter words starting with Q. I was wondering why it was so hard!
Northern Virginia native, can't believe I missed the FBI crime lab question... probably would have gotten it if the clue was something about the Marine Corps, though I realize there's a TV show about the FBI based there I've never seen it.
I recommend you guys change the Queluz hint to "Town near Queluz famous for its Versailles-like palace". No one in Portugal sees Queluz as a city in its english definition, and even I, a Portuguese had no idea it was going to be Queluz.
