Explanation:
- **Tragedy Degree (6):** The story contains significant tragic elements, primarily due to the loss of Marissa's husband, Kevin, and her ongoing struggle with grief. This emotional setback is a central part of her character and the narrative, giving the story a moderate to high degree of tragedy.
- **Comedy Degree (2):** The story lacks comedic elements and is predominantly serious and intense. The positive ending provides a sense of relief and subtle emotional lift, but it is not particularly light-hearted or humor-infused, hence the low comedy degree rating.
