The story you've provided has mild humorous elements and very minor setbacks, making it light-hearted with a generally positive tone.

Here's the evaluation based on the criteria:

- Tragedy Degree: The story has almost no tragic elements. The most significant challenge is Mr. Dawson dealing with his stubborn donkey, which is more of a light-hearted inconvenience than a tragedy. Thus, it warrants the lowest score on the tragedy scale.
- Comedy Degree: The story has modest comedic elements, notably in Jasper the donkey's antics and the way the neighbors react. However, it is not exceedingly funny or emotionally delightful, thus it rates slightly above average on the comedy scale.
