BP317 Number of enclosed black circles varies in correlation with enclosing circle outline size vs. not so.
(edit; present; nest [left/right]; search; history)
COMMENTS

This is a Bongard Problem about comparing something discrete (number) with something continuous (size).


The inner black circles vary in size randomly. (This forces the solution to be about the discrete number of black circles instead of their combined area.)
