An author might choose to use a chronological structure when writing a biography in order to present the subject's life in a clear and organized manner. By following a chronological order, the author can present events in the subject's life in a logical sequence, allowing the reader to easily follow their journey from birth to present. This structure also helps the author to highlight the key milestones and events in the subject's life, showing how they have shaped and influenced their development and achievements over time. Additionally, a chronological structure can create a sense of progression and momentum, building towards climax and resolution as the subject's life story unfolds.
