The author's approach to the subject matter is primarily that of

Analysis involves breaking down information into parts to understand it better or to evaluate different components. While the author presents information about training dogs and horses, the focus is not on dissecting these elements but rather on merging stories with factual content to create a cohesive understanding. Thus, analysis does not accurately represent the author's approach.

Detailed reportage refers to in-depth reporting that typically emphasizes factual presentation and objectivity. Although the author includes factual elements about animal training, the incorporation of narrative techniques and storytelling indicates a broader synthesis rather than a strict factual recounting. Therefore, this choice does not align with the author's blended approach.

Descriptive narration focuses on vividly conveying scenes and experiences through storytelling. While the author uses narrative elements, the main goal is to synthesize these narratives with informational content rather than simply describe them. As such, descriptive narration fails to capture the essence of the author's method.
