Here is a short Python program.

```python
cells = [5, 9]
depth = 1
peak = 6
peak = len(cells) // 4
cells.append(peak)
cells.append(depth * 2)
```

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

Let's trace the execution of the Python code step by step:

1. `cells = [5, 9]` initializes a list named `cells` with the values 5 and 9.
2. `depth = 1` assigns the value 1 to the variable `depth`.
3. `peak = 6` assigns the value 6 to the variable `peak`.
4. `peak = len(cells) // 4` calculates the integer division of the length of `cells` (which is 2) by 4.  2 // 4 is 0. So, `peak` is updated to 0.
5. `cells.append(peak)` appends the value of `peak` (which is 0) to the end of the `cells` list. `cells` becomes `[5, 9, 0]`.
6. `cells.append(depth * 2)` appends the value of `depth` (which is 1) multiplied by 2 to the end of the `cells` list. 1 * 2 is 2. `cells` becomes `[5, 9, 0, 2]`.

Therefore, the final value of `cells` is `[5, 9, 0, 2]`.

ANSWER: [5, 9, 0, 2]
