 2      I, 11|     A belongs to none of the Cs, while C belongs to some
 3      I, 14|     Bs, and B to none of the Cs. No syllogism results from
 4      I, 14|    may belong to some of the Cs, it is necessary that A
 5      I, 14|    not belong to some of the Cs. The proof is the same as
 6      I, 16|    may belong to some of the Cs, it is necessary that A
 7      I, 16|    not belong to some of the Cs. For if A belongs to all
