Here is a short Python program.

```python
spare = 7
items = [3, 4, 5]
stack = [4, 5, 6, 7]
items.append(spare)
spare += len(items)
spare += stack[0]
```

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

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

1.  `spare = 7`
    *   `spare` is now **7**.
2.  `items = [3, 4, 5]`
    *   `items` is a list with 3 elements.
3.  `stack = [4, 5, 6, 7]`
    *   `stack` is a list with 4 elements.
4.  `items.append(spare)`
    *   The value of `spare` (7) is added to the end of the `items` list.
    *   `items` is now `[3, 4, 5, 7]`.
5.  `spare += len(items)`
    *   `len(items)` is now 4.
    *   `spare = 7 + 4`
    *   `spare` is now **11**.
6.  `spare += stack[0]`
    *   `stack[0]` is the first element of the `stack` list, which is 4.
    *   `spare = 11 + 4`
    *   `spare` is now **15**.
