D. Mangan's sister sets the hero's quest in motion when she requests a gift from the bazaar.
Explanation:
In this story, the protagonist is a young boy who is beginning to become interested in girls. Although he knows very little about the opposite sex, he becomes interested in Mangan's sister. In order to prove his love, he decides to bring her a gift from the bazaar called "Araby." Therefore, this is the impact that the "pure maiden" has in the story, as her presence sets the hero's quest in motion.
i dont think there is any reason. you might find that the author has the same themes that he/she likes to write about but idk i think you need to read the book
