- **Tragedy Degree (3):** The story has a few minor tragic elements, such as Dr. Evelyn Ross's personal connection to diabetes through her brother and the challenges faced by the researchers. However, these elements are not deeply profound or highly emotional setbacks, so the overall tragedy degree remains low.

- **Comedy Degree (6):** The story ends on a relatively uplifting and hopeful note with the major breakthrough in diabetes research, evoking feelings of joy and accomplishment. While it isn't extremely comedic in nature, it is emotionally delightful and has more light-hearted elements than tragic ones.
