One possible theme could be abundance or scarcity. Since there are seventeen oranges, it could be about having enough (abundance) or not having enough (scarcity) depending on the context of the story. For example, if the characters are starving, seventeen oranges might be a lot, but if they are a large group, it might not be enough.
The theme of value could also be present in the 'Seventeen Oranges' short story. Are the oranges valuable in the story's world? Are they just ordinary fruits or do they hold some special significance? If they are valuable, it could lead to themes of greed and protection. If they are not, it might be about how we perceive the worth of things. Additionally, a theme of change could be there. Maybe the seventeen oranges change in some way, like they start to rot or they are magically transformed, which could symbolize change in the characters' lives or the world of the story.
