Bongard Problems

Info on Bongard Problems

Long story short, you have to figure out what the left side items have in common that the right side items lack.

I was thinking it might be fun to pose Bongard problems to each other, but to make things easier, it might be better to do textual ones, like this:

Group A:

try
sum
not
let
nil
won


Group B:

house
monkey
nachos
trim
blonde
Mag!cGuy

Now, surely the solution is that Group A contains words with exactly three letters, while Group B contains words with a number of letters that is not three. That is an easy example.

Here's one to start with:

Group A:

Italy
Yemen
Germany
Egypt
Cyprus
Malaysia


Group B:

Georgia
France
Wales
Mexico
Honduras
Canada
