Hi! If a sufficient condition can point to two necessary conditions, you can say there is a "some" relationship between those two necessary conditions. So if X -> Y and X-> Z, you can say that some Y are Z and some Z are Y. This also works further out in the chain.
Here you have clerks -> talk and you have baseball moms -> soccer moms -> talk. If you take the contrapositive, /talk -> /clerk and /talk -> /soccer mom -> /baseball mom, you can create "some" conclusions between /clerk and /soccer mom and between /clerk and /baseball mom.
