Here is a short Python program.

```python
limit = 7
base = 8
parts = [3, 8, 3, 4]
if base == base:
    parts = parts + [limit]
if base >= base:
    limit += len(parts)
else:
    base = base + 1
base = parts[0]
parts[0] = base
limit += base
```

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

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

1.  **Initialization:**
    *   `limit = 7`
    *   `base = 8`
    *   `parts = [3, 8, 3, 4]`

2.  **First `if` statement:**
    *   `if base == base:` (8 == 8) is **True**.
    *   `parts = parts + [limit]` $\rightarrow$ `parts = [3, 8, 3, 4] + [7]` $\rightarrow$ `parts = [3, 8, 3, 4, 7]`

3.  **Second `if/else` statement:**
    *   `if base >= base:` (8 >= 8) is **True**.
    *   `limit += len(parts)` $\rightarrow$ `limit = 7 + 5` (since `parts` now has 5 elements) $\rightarrow$ `limit = 12`
    *   The `else` block is skipped.

4.  **Final assignments:**
    *   `base = parts[0]` $\rightarrow$ `base = 3` (the first element of `[3, 8, 3, 4, 7]`)
    *   `parts[0] = base` $\rightarrow$ `parts[0] = 3` (no change to the list)
    *   `limit += base` $\rightarrow$ `limit = 12 + 3` $\rightarrow$ `limit = 15`

**Final values:**
*   `limit` = 15
*   `base` = 3
*   `parts` = [3, 8, 3, 4, 7]
