Final answer:
The author of "The Oasis: Africa" organized the narrative thematically, focusing on topics like politics and economics and their connection to Africa's geography and climate.
Step-by-step explanation:
The author of "The Oasis: Africa" organized events in the narrative thematically. While some narratives follow a chronological sequence, this particular text opts for a thematic structure, likely focusing on topics such as politics, economics, religion, or language as they pertain to Africa. These themes are treated with geographic consideration, possibly using vignettes or case studies to illustrate how different parts of Africa are viewed through the lens of these themes.
The thematic organization allows the author to discuss concepts spatially and temporally, highlighting how geography and climate have influenced social, political, economic, and cultural impacts across different regions of Africa. As the materials treat different topics or regions over the same time period in separate chapters, this thematic approach seems to take precedence over a strictly chronological arrangement.
