Some Before are Opposite (I) → Conversion → Some Opposite are Before (I) + All Before are After (A) → Some Opposite are After (I) → Conversion → Some After are Opposite (I). Hence conclusion I follows. All Before are After (A) + All After are Behind (A) → All Before are Behind (A) → Conversion → Some Behind are Before (I). Hence conclusion II follows. Some Opposite are After (I) + All After are Behind (A) → Some Opposite are Behind (I). Hence conclusion III does not follow.
