Which novel is **NOT** an allegory?

George Orwell's "Animal Farm" is a well-known allegory that uses a farm and its animal inhabitants to symbolize the events leading up to the Russian Revolution and critiques totalitarianism. The characters and events within the story represent real historical figures and ideologies, making it a prime example of allegorical literature.

"Quicksand," written by Nella Larsen, explores themes of race, identity, and social constraints in early 20th-century America. While it addresses significant social issues, it does so through the personal experiences of its characters rather than using symbolic representation to convey a broader moral or political message, which aligns it closer to allegory.

Richard Adams' "Watership Down" is often viewed as an allegory for the human condition, exploring themes such as leadership, community, and survival through the lens of a group of rabbits. The narrative employs animals to reflect complex social dynamics and philosophical ideas, embodying allegorical elements.

J.R.R. Tolkien's "The Lord of the Rings," while containing deep themes and moral questions, is not strictly an allegory. Tolkien himself stated that the story’s elements were not meant to symbolize specific real-world events or ideologies, focusing instead on universal themes of good versus evil, friendship, and sacrifice.
