Image of a Bongard Problem such that the bottom left box rules out a solution vs. no single box affects the solution.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`When removal of a box changes the solution, it cannot remove the existing solution; it can only allow more possible new solutions. Conversely, adding boxes can only narrow down between existing solutions.` `The special box is always placed in the bottom left for help, but another solution is "there is some box whose removal allows another solution vs. not".` `Bongard Problems sorted left might be called "deceptive". Especially when the solution ruled out by the one box is the more obvious solution.`
