Here is a short Python program.

```python
peak = 2
text = 'ab'
title = 'cat'
peak += len(text)
title = title + 'ab'
peak += len(title)
```

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

To find the value of `peak`, let's trace the program step by step:

1.  `peak = 2`
    *   `peak` is now `2`.
2.  `text = 'ab'`
    *   `text` is now `'ab'`.
3.  `title = 'cat'`
    *   `title` is now `'cat'`.
4.  `peak += len(text)`
    *   `len(text)` is `len('ab')`, which is `2`.
    *   `peak = 2 + 2`, so `peak` is now `4`.
5.  `title = title + 'ab'`
    *   `title = 'cat' + 'ab'`, so `title` is now `'catab'`.
6.  `peak += len(title)`
    *   `len(title)` is `len('catab')`, which is `5`.
    *   `peak = 4 + 5`, so `peak` is now `9`.

The final value of `peak` is 9.
