Final answer:
Ender Wiggin beats the Giant in 'Ender's Game' by outsmarting it, attacking the Giant directly rather than choosing between the drinks offered in the virtual reality challenge.
Step-by-step explanation:
The question refers to events from the book Ender's Game by Orson Scott Card. In this science fiction novel, the protagonist, Ender Wiggin, faces numerous challenges at Battle School, including a virtual reality game with a seemingly unbeatable level known as the Giant's Drink.
Ender eventually beats the Giant by outsmarting it. Instead of choosing between the drinks offered by the Giant—which would result in endless deaths in the game—Ender breaks the rules of the game by attacking the Giant directly, climbing into its face and digging into the Giant's eye, effectively killing it and discovering a new area of the game previously unseen by any other player.
