Based on the scoring criteria provided, here is the evaluation of the story:

**Tragedy Degree:**
- The story involves a situation of distress and urgent rescue, but it doesn't present profound or severe tragedy. Emotional setbacks are present, such as the urgency and the lives of innocent people at risk. However, the successful outcome mitigates the potential for a high tragedy score.
- A score of 4 is appropriate, reflecting moderate tragic elements without a deep emotional impact.

**Comedy Degree:**
- The story is primarily serious and tense, focusing on a high-stakes rescue mission rather than elements of comedy or light-heartedness. The ending is successful and happy, but it is more of a relief than comedic.
- A score of 1 is appropriate, indicating an almost complete lack of comedic elements.

Therefore, the JSON output is:

```json
{
  "TragedyDegree": 4,
  "ComedyDegree": 1
}
```
