Based on the provided story, here is the evaluation of its Tragedy Degree and Comedy Degree:

Tragedy Degree:
- The story does not contain significant tragic elements such as loss or major setbacks. There is a sense of urgency and challenge, but it is largely about overcoming obstacles rather than dealing with profound tragedy.
- Thus, it falls closer to the lower end of the scale for tragedy.

Comedy Degree:
- The story has a relatively positive, uplifting conclusion where the community comes together and successfully overcomes the challenge. However, it is not centered on comedic elements or humor. The happiness stems from problem-solving and support rather than comedic aspects.
- As a result, its comedy degree is moderate, focused more on a happy outcome than on humor.

Given these considerations, here's the evaluation in JSON format:
