Question

Manny realizes that the castle described in the book he is reading stands for a larger idea: paradise. Which literary device is the author using?

Answer 1

The correct answer should be a "Metaphor".

This is a metaphor because when an element is used to evoke an imagination or a deeper understanding of another element it is called a metaphor. In this case, the castle is a metaphor for paradise, because paradise is what it really means.
