It was a challenge about inheritance. The correct answer is ‘bananas’ because when a function is called that is defined multiple times in different contracts, parent contracts are searched from right to left. The override(Ship_B, Ship_A) part gives the false impression of a locally determined inheritance ordering, but it does not actually influence it.

Nice challenge!

spoiler

Seems like the last mentioned contract in the is Ship_A, Ship_B part determines which one super refers to when they have matching function names.
