From I. All Instagram are Google (I) → Conversion → Some Google are Instagram (I) + Only a few Instagram are Facebook (I) → No conclusion. Hence conclusion II does not follow. Some Twitter are Google (I) + [All Instagram are Google (I) → Conversion] → Some Google are Instagram (I) → Probable conclusion → All Twitter can be Instagram (A). Hence conclusion II follows. From II. Some Facebook are Instagram (I) + All Instagram are Google (A) → Some Facebook are Google (I). Hence conclusion I does not follow. All Twitter are Facebook (A) + Some Facebook are Instagram (I) → No conclusion. Hence conclusion II does not follow. From III.
