What is the most crucial characteristic of the explanation section in a written work?

The explanation section in a written work primarily serves to clarify and elaborate on the main ideas presented in the text. For this purpose, providing examples and evidence that support the argument is essential. This characteristic is crucial because it allows the reader to understand not just the claim being made, but also the rationale behind it. Engaging evidence and relevant examples help to substantiate the author's arguments, making them more compelling and credible. By illustrating how the argument operates in practice, and by anchoring it with specific data or case studies, the writer effectively enhances the reader’s comprehension and belief in the validity of the assertions.

In contrast, a summary of the text focuses solely on a recapitulation of the main points without deeper analysis. Personal reflections by the author may provide insight into their experiences or views but do not necessarily strengthen the logical foundation of the argument. Predictions for future outcomes, while interesting, do not directly contribute to explaining the content of the work and the rationale behind its arguments; they are more speculative and not as pivotal to the immediate understanding of the current text. Thus, examples and evidence stand out as the most vital characteristic in the explanation section.
