    Some apples are oranges (I) + Each orange is grapes (A) → Some apples are grapes (I) → Conversion → Some grapes are apples (I) + Some apples are mangoes (I). Hence conclusion I does not follow. Some apples are oranges (I) → Conversion → Some oranges are apples (I) + Some apples are mangoes (I) → No conclusion. Hence conclusion II does not follow. Only apples is kiwi → All kiwi are apples and kiwi cannot have positive relation with anyone. Hence conclusion III follows.
