	COMMENTS	`Left-sorted problems have the keyword "finishedexamples" on the OEBP.` `The addition does not have to be slight.` `Left-sorted Problems usually have a very specific collection of examples, where the only images sorted all show the same type of object.` `Any Bongard Problem where all examples are one shape outline will be sorted left, and (almost) any Bongard Problem where all examples are one fill shape will be sorted right.`
	CROSSREFS	`See BP1144 for the version about both additions and erasures, and only slight changes are considered.` `See BP1167 for a stricter version, the condition that all examples have the same amount of black and white.` `Adjacent-numbered pages: BP1137 BP1138 BP1139 BP1140 BP1141 * BP1143 BP1144 BP1145 BP1146 BP1147`
