Based on the provided story, here is the assessment of its Tragedy Degree and Comedy Degree according to the specified criteria:

1. **Tragedy Degree**: The story clearly contains tragic elements, including Marla's accident and subsequent struggle with recovery. There is an emotional element tied to her hardships and the efforts to reclaim her life. However, these elements are not overwhelming or deeply sorrowful, as the narrative focuses more on hope and determination rather than despair.

2. **Comedy Degree**: There are positive and uplifting elements in the narrative, particularly Marla’s determination and the support from her husband, Ed. However, the story lacks explicit comedic elements or a traditionally happy ending with strong comedic aspects. While it is hopeful and inspiring, it doesn’t qualify as heavily comedic.

Here are the scores in JSON format:

```json
{
  "TragedyDegree": 5,
  "ComedyDegree": 3
}
```

These ratings reflect the moderate level of tragedy due to Marla’s injury and recovery process, and a lower comedy degree due to the absence of significant comedic elements.
