Here is a short Python program.

```python
offset = 5
codes = [1, 5, 8]
scores = [7, 0, 5]

def scale(val):
    k = val + 4
    return k * 2

codes.append(offset)
if offset > 8:
    offset += len(codes)
codes.extend([offset, 3])
scores = scores[1:]
offset += len(scores)
offset = scores.pop()
```

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

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

1.  **Initialization:**
    *   `offset = 5`
    *   `codes = [1, 5, 8]`
    *   `scores = [7, 0, 5]`

2.  **Function Definition:**
    *   `scale(val)` is defined but never called in the script.

3.  **`codes.append(offset)`:**
    *   `offset` is 5.
    *   `codes` becomes `[1, 5, 8, 5]`.

4.  **`if offset > 8:`:**
    *   `offset` is 5.
    *   `5 > 8` is `False`. The block inside the `if` statement is skipped.

5.  **`codes.extend([offset, 3])`:**
    *   `offset` is 5.
    *   `codes` becomes `[1, 5, 8, 5, 5, 3]`.

6.  **`scores = scores[1:]`:**
    *   `scores` was `[7, 0, 5]`.
    *   Slicing from index 1 to the end results in `[0, 5]`.

7.  **`offset += len(scores)`:**
    *   `len(scores)` is 2.
    *   `offset = 5 + 2 = 7`.

8.  **`offset = scores.pop()`:**
    *   `scores` is `[0, 5]`.
    *   `.pop()` removes and returns the last element of the list.
    *   The last element is `5`.
    *   `offset` becomes `5`.

Final value of `offset` is 5.
