Write a foreword to Jomo Kenyatta's Facing Mount Kenya: The Tribal Life of the Gikuyu. In it, make connections between concepts from the lesson — namely job specialization and social stratification — and the book that readers are about to study. Your job is to encourage readers to think about Kenyatta's account in the context of history. Your foreword should include an introduction paragraph with a general statement about what historians can learn about job specialization and social stratification in Neolithic times from the Gikuyu people, as described by Kenyatta. Your foreword should also include several body paragraphs that go into more detail, citing examples from the reading. Finally, your foreword should end with a conclusion paragraph that reminds readers of your overall point and encourages them to read the book.
