Object comparison Problems where every example establishes its own distinct "world" of allowed objects vs. object comparison Problems where every example pulls from the same set of allowed objects.

Object comparison Problems where every example establishes its own distinct "world" of allowed objects vs. object comparison Problems where every example shares the same set of allowed objects to pull from.

Left-sorted Problems have the keyword "miniworlds" on the OEBP.

There is a decent degree of overlap between "rules" Problems and left-sorted examples here, but

BP1049 is an example of a "miniworlds" problem where the rule is constant across examples, and BP1155 is an example of a "rules" Problem that would be sorted right (if anywhere) here.

TO DO: Develop this and see whether it should replace BP1175 entirely. If BP1175 is kept, it should probably only concern itself with Problems that could easily be reskinned to be sorted on its other side.
