Final answer:
The text features that include introductions, summaries, headings, footnotes, endnotes, and author information are called Organizing features.
Step-by-step explanation:
The type of text feature that uses introductions, summaries, sections with headings, footnotes, endnotes, and information about the author is known as Organizing features. These tools help to structure the content of a text, making it easier for readers to follow and understand complex information. Organizing features like these are essential for guiding a reader through various parts of a text and can often be found in academic writings, non-fiction books, and comprehensive reports.
Another aspect of these organizing features is the capacity to enhance reader comprehension. For instance, sections with headings allow readers to identify the main points of each part of the text. Similarly, introductions and summaries provide a quick overview and a concluding overview of the material, respectively. Footnotes and endnotes offer additional information or citations without cluttering the main body of the text, and information about the author establishes credibility and context.
