I just asked my wife and (29 yr old) daughter to do the puzzle, and both of them said exactly the same thing - what are you supposed to do?
It's a spacial awareness puzzle, and at the risk of being accused (again) of being sexist, women commonly do very badly in such tests. In the same way that men do badly in multi-tasking situations. Nobody's fault, just one of those things.
If I see one overtly sexist post following this I'll delete the thread.
