Intersectionality?

[Marcas]

I have reading two books The absolutely true dairy of a part time diary and Persepolis by Marjane Satrapi

I do not understand the concept or the breakdown of intersectionality? Can somebody please explain?
If anyone read the two books and found any examples of intersectionality?

My assignment is to Compare and contrast the representation of two of the following identity categories-gender,race,class,sexuality, indigeneity and or disability in two texts. In your answer, pay attention to the concept of intersectionality?

The autobiographic novels Persepolis by Marjane Satrapi and Absolutely True dairy of part time Indian by Sherman Alexie examines the themes of gender, race, class, sexuality, indigeneity through the concept of Intersectionality. Marjane Satrapi’s Persepolis invites readers on a journey back to her childhood in Iran in the late 1970s and throughout the 1980s. The novel follows young Marji through her young years as an outspoken, free-thinking, defiant young girl in the face of extreme governmental censorship and persecution. Similar to Sherman Alexie’s novel Absolutely True dairy of part time Indian, we are introduced to Arnold Spirit, Jr a teenage native Indian that lives in poverty on Spokane Indian Reservation with his two alcoholic parents.’
