Can any of the 3 large circles have a rule that includes 2 properties rather than just 1, ie both color and shape?
If not, I ask that you verify the answers given so far since I think one may be incorrect.
Hmm, do the 3 rules have to allow overlap, or can rules contradict one another, ie one rule has lines, another rule has no lines?
Here is a guess. Is spot 7 empty?
