This is the keyword "metaworld" on the OEBP.

Left examples sort all Bongard Problems and thus have "world" Bongard Problems (i.e. fit on left-BP524).

Many BPs are sorted leftly by only one MBP that is a left example for this MMBP. A BP most naturally has one specific world.

However, in many cases it is ambiguous what the most obvious choice of "world" for a BP is.

For example, is the "world" of BP6 "polygons" or "triangles and quadrilaterals"? The fact that all examples shown are triangles and quadrilaterals does make the solver parse the pattern of all the images together as "triangles and quadrilaterals," but that specific detail might not be considered important enough to mention; the obvious simple collection both sides fall into is "polygons." In these MBPs about worlds, we will err on the side of inclusion: it is okay to indicate a BP has more than one world if the situation is ambiguous, as in this example.

However, do not arbitrarily include worlds that are too big; the world of BP6 is not "shapes."
