Step-by-step explanation:
South American Magic Realism was heavily influenced by the literary movement of Latin American "boom" writers such as Gabriel García Márquez, Jorge Luis Borges, and Isabel Allende. These writers incorporated aspects of magical realism in their work, which is a style of writing that combines fantastical elements with realistic detail. The genre of magical realism is exemplified by Gabriel García Márquez's novel One Hundred Years of Solitude, which tells the story of the Buendía family in the fictional town of Macondo. The narrative of the novel moves in a circular shape, representing the cyclical nature of time and history.
