**Explanation**:

- **Tragedy Degree: 2**: The story has a relatively low degree of tragedy. While it does portray a sense of isolation and the daunting task faced by Dr. Elena Sloane, it does not present profound emotional setbacks or tragic events. Her journey is challenging but ultimately leads to a positive and fulfilling discovery.

- **Comedy Degree: 3**: The story contains minimal comedic elements. It is neither light-hearted nor filled with humor; it instead focuses on the serious and scientific endeavors of Dr. Elena Sloane. There is a sense of accomplishment and fulfillment, but it falls short of being a joyous or extremely happy tale.
