"In general, younger Americans tended to provide more accurate responses than their older counterparts: 27 percent of 18-24 year olds correctly identified Ukraine, compared with 14 percent of 65+ year-olds."
65+ year olds spent a big chunk of their lives in the cold war. Presumably they would know more about the geographical breakup of the Soviet Union than 18-24 year olds who didn't even exist when the Berlin Wall fell.
From a data analysis standpoint, I would say discard the outliers that look like mis-clicks. Based on the groupings you still have people that identified Alaska, Greenland, Canada, India South America, and so on. Irregardless of the colorings or map size, those should not have been chosen.
On another note, a given countries foreign policy always makes a hell of a lot more sense when placed in context on a map. I'm glad I read a lot of National Geographic as a child.
