How did you answer Question 3? 

When I did it, it generated a picture with a number of blocks of code in it (Q3 effectively being "how many blocks?"). Q4 is just asking, "What's the starting address of the final ('last') block of code on that diagram"?

    Yes.  In the graph there are 2 "legs" going down - sort of an inverted 'Y'.  I entered the starting address of the bottom block on each leg.  Neither is correct.

      I'm not convinced you're looking in the right place/at the right thing - what I'm seeing looks nothing like an inverted Y... I don't want to post the entire diagram, but the outline of the function graph I'm seeing looks like this (the box at the bottom is what you're looking for): 

      Are you sure you're looking at the correct function (there's a pointer in the info pane to where the  main user defined function is located)?
