Answer:
Gilgamesh picks the plant described by Utnapishtim because he wants it to grant him eternal youth and immortality. In the epic of Gilgamesh, Gilgamesh is a heroic figure who is confronted with the reality of his own mortality. He seeks the plant in the hopes that it will bestow upon him the gift of eternal life, allowing him to escape the fate of death.
Now let's analyze the physical characteristic of a snake that makes it work well as the character who ends up benefiting from the plant.
One physical characteristic of a snake that makes it suitable for the character who benefits from the plant is its ability to shed its skin and renew itself. In many cultures, the snake is associated with regeneration and rebirth due to this unique characteristic. Similarly, in the epic of Gilgamesh, the snake is portrayed as the creature who ultimately benefits from the plant that grants eternal youth.
The snake's ability to shed its old skin and emerge with a fresh one is seen as a metaphor for rejuvenation and renewal. This aligns with the theme of immortality and eternal youth present in the epic. The snake's association with shedding and renewal makes it fitting that it is the one who takes possession of the plant, symbolizing the cycle of life and death.
In conclusion, Gilgamesh picks the plant because he desires eternal youth and immortality, and the snake is a suitable character to benefit from the plant due to its association with regeneration and renewal through shedding its skin.
