All Saucers are Cups (A) → Conversion → Some Cups are Saucers (I) + No Saucers are Plates (E) → Some Cups are not Plates (O). Hence conclusion I follows. Some Cups are not Plates (O) + All Plates are Spoons (A) → Probable conclusion → All Spoons can be Cups (A). Hence conclusion II follows. No Saucers are Plates (E) + All Plates are Spoons (A) → Some Spoons are not Saucers (O*). Hence conclusion III does not follow.
