Where does Julia alvarez show circular nattartive in her text In the time of the butterflies?

In the Time of the Butterflies is divided into three sections of four chapters each. Each part opens with Dede in third-person narration whereas the narration is given in the first person for the other sisters. Dede’s chapters are divided into two parts: 1994 (the present) and the past, when her sisters were alive, beginning with 1943. The time frame of the "present" is a span of one afternoon, in which Dede gives an interview. But the interviewer’s questions transport Dede, and the reader, back in time and into the consciousnesses of the sisters. Each circular narration picks up different details of the story.
