### Task 1a - stop the code right before `question` is assigned. What is the current context?
### Task 1b - step into the function using s(tep). What is the next line to be executed?
### Task 1c - rerun the example and this time go to the n(ext) line. What is the next line to be executed?

### Task 2 - Stop the code in the same place as before. S(tep) into the get_question function and
# enter n(ext) to get to line 30. S(tep) again. What function do we end up in?

### Task 3a - Stop the code in the same place as before. Print out w(here) you are. How many frames are in the stack?
### Task 3b - Rerun the example and step into the next function. Use the w(here) command again. How many frames are there now?
### Task 3c - Now put a breakpoint in `get_questions`. Navigate u(p) and d(own) in the frame. How many u(p) commands is it to the top of the stack?
