Here's why it's not science fiction or fantasy:
* Science Fiction: Treasure Island doesn't involve futuristic technology, space travel, or other elements typically found in science fiction.
* Fantasy: While there's some element of the unknown (like the treasure and the pirates), the story is rooted in reality. It's not based on magic, mythical creatures, or supernatural powers.
Treasure Island's key elements include:
* Historical setting: The story takes place in the 18th century, during the golden age of piracy.
* Realistic characters: The characters are mostly believable, with flaws and motivations that feel grounded in reality.
* Action and adventure: The story revolves around a thrilling journey filled with danger, suspense, and unexpected encounters.
So, while Treasure Island is certainly imaginative and full of adventure, it's considered adventure fiction, not science fiction or fantasy.
