Some summers are springs (I) → Conversion → Some springs are summers + All summers are winters (A) → Some springs are winters (I) → Conversion → Some winters are springs (I). Hence conclusion I follows. Some springs are autumn (I) + No autumn is season (E) → Some springs are not seasons (I). Hence conclusion II follows.
