Here is a short Python program.

```python
score = 7
stack = [2, 5, 8]
batch = [5, 7, 3]
stack = stack + [4]
score += stack[-1]
score += batch[0]
```

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

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

1.  `score = 7`: The variable `score` is initialized to **7**.
2.  `stack = [2, 5, 8]`: A list `stack` is created.
3.  `batch = [5, 7, 3]`: A list `batch` is created.
4.  `stack = stack + [4]`: The list `[4]` is concatenated to `stack`.
    *   `stack` becomes `[2, 5, 8, 4]`.
5.  `score += stack[-1]`: The last element of `stack` (`stack[-1]`) is added to `score`.
    *   The last element of `[2, 5, 8, 4]` is **4**.
    *   `score = 7 + 4 = 11`.
6.  `score += batch[0]`: The first element of `batch` (`batch[0]`) is added to `score`.
    *   The first element of `[5, 7, 3]` is **5**.
    *   `score = 11 + 5 = 16`.

The final value of `score` is 16.
