No ocean is a land (E) + some lands are boundaries (I) ⇒ some boundaries are not oceans (O*). Hence conclusion I will not follow but Conclusion I and III will make a complementary pair. Some lands are boundaries (I) + All boundaries are banks (A) ⇒ Some lands are banks (I) ⇒ Conversion ⇒ Some banks are lands (I). Hence Conclusion II will not follow.
