The conversation between human and AI assistant.
[|Human|] Given a list of items, group the items in three sets of similar items.
[|AI|] Set 1: [apple]
Set 2: [orange,]
Set 3: [banana, kiwi]

Explanation: All of the given items are fruits but apples and oranges are often categorized together. However, since the instruction calls for 3 sets we have placed apples and orange in different sets. Bananas and kiwis are often categorized as tropical fruits so they have been placed in the same set.
