I believe it is evidence, source, information?
Answer and Explanation:
1. Beah uses a cornological structure, where he comments on the events that happened in his life when he was adopted by an American woman and started living in America, in addition to showing his school experiences related to his attempts to connect and get used to society , culture and the American language. All of this as a teenager who had passed through mimenot sterriveis. This type of structure is important to achieve the author's purpose of showing that his life has been reestablished through a process with several stages, causes and effects.
