Answer:
paper.
Step-by-step explanation:
"Fahrenheit 451" is a book authored by Ray Bradbury. The novel is about the future of American society where books are banned now, and a fireman had been hired to burn all the books to be found. Even the places where books are kept. The tagline of the book explains the title of the book: "the temperature at which book paper catches fire, and burns..." Guy Montag is the protagonist of the story, who has been hired to burn down all the literature. But as the story makes progress we see that Guy quits his job of a firemen and eventually starts preserving the cultural writings and literature.
