Here is a short Python program.

```python
level = 5
limit = 5
delta = 4
level += delta
delta = limit - 9
delta += 9

def scale(v):
    m = v + 5
    return 2 * m

values = [3, 5, 6]
parts = values
parts += [16]
parts = parts + [22]
rows = values[:]
rows.append(31)
level += len(values) + values[-1]
extra = 1
offset = 0
while extra < 41:
    extra += 5
    offset += 1
level += offset + extra
level += limit
```

After this program runs, what is the value of `level`? Work through it carefully, then give the final answer on its own last line as `ANSWER: <python literal>`.

To find the final value of `level`, let's trace the program step-by-step:

1.  `level = 5`
2.  `limit = 5`
3.  `delta = 4`
4.  `level += delta` $\rightarrow$ `level = 5 + 4 = 9`
5.  `delta = limit - 9` $\rightarrow$ `delta = 5 - 9 = -4`
6.  `delta += 9` $\rightarrow$ `delta = -4 + 9 = 5`
7.  The function `scale(v)` is defined but never called.
8.  `values = [3, 5, 6]`
9.  `parts = values` (Both point to the same list object)
10. `parts += [16]` $\rightarrow$ `values` is now `[3, 5, 6, 16]`
11. `parts = parts + [22]` $\rightarrow$ `parts` is now a new list `[3, 5, 6, 16, 22]`, but `values` remains `[3, 5, 6, 16]`
12. `rows = values[:]` $\rightarrow$ `rows` is a copy: `[3, 5, 6, 16]`
13. `rows.append(31)` $\rightarrow$ `rows` is `[3, 5, 6, 16, 31]`, `values` is still `[3, 5, 6, 16]`
14. `level += len(values) + values[-1]`
    *   `len(values)` is 4.
    *   `values[-1]` is 16.
    *   `level = 9 + 4 + 16 = 29`
15. `extra = 1`
16. `offset = 0`
17. `while extra < 41:`
    *   Iteration 1: `extra = 6`, `offset = 1`
    *   Iteration 2: `extra = 11`, `offset = 2`
    *   Iteration 3: `extra = 16`, `offset = 3`
    *   Iteration 4: `extra = 21`, `offset = 4`
    *   Iteration 5: `extra = 26`, `offset = 5`
    *   Iteration 6: `extra = 31`, `offset = 6`
    *   Iteration 7: `extra = 36`, `offset = 7`
    *   Iteration 8: `extra = 41`, `offset = 8`
    *   Loop terminates because `extra < 41` is now false.
18. `level += offset + extra`
    *   `level = 29 + 8 + 41 = 78`
19. `level += limit`
    *   `level = 78 + 5 = 83`
