@98765 The contra-positive of b-some-c is c-some-b.

Think of it this way. If you have 10 objects that are B, C, both, or neither, and there are a total of 6 Cs and 6 Bs whether in combination or not, you can say that some Bs are Cs because there will have to be some overlap. But from the premise that some Bs are Cs you can only conclude that some Cs are Bs. It's possible that most Cs are Bs, but it's not guaranteed by the argument.
