ADOS-2 module 4 (adults)

So I have just done the ADOS module 4, how very strange! I got the point of the questions, they all seemed relevant. I really didn’t get the other activities, they seemed to be for kids? I did query with them and said is this definitely for adults and they said yes it was. The puzzle my 5 year old could have done. Not sure what that was about. 
Don’t want to put too much in case anyone is awaiting doing the tests but anyone who’s done the ADOS module 4, any thoughts on what they were looking for with the tasks?
