Oh a bug, surely. How is the quiz supposed to give you insights when it's unanswerable?
Similar to how when presented with the trolley problem some will ask many follow up questions about the individuals on each track, the train, etc.
That’s not the point.
Not the OP, but what would be the point to that? In any practical scenario there is always context, isnt it? I guess I don't quite get what we are trying to measure here.
