Most such questions can be answered by printing out the values in 
question and observing first hand what the value is.

So, print out box.sort() to see what it is.  You might be surprised.

Hint: box.sort() does indeed cause box to be sorted, and the sorted list 
is left in box, but the sorted list is not returned as a function value.
