	*a set* is a subset of *a set*,
	*a thing* is a set,
	*a thing* belongs to *a set*.

the knowledge base subsets includes:

a set A is a subset of a set B

scenario one is:
	family one is a set.
	family two is a set.
	Bob belongs to family one.
	Alice belongs to family one.

	Alice belongs to family two.

query one is:
 	which first family is a subset of which second family.

	[Alice] is a set.

	a thing belongs to a set
    if the thing is in the set.
