The features that help readers create an outline as they take notes are primarily headings and subheadings. These elements provide a clear structure to the content, making it easier for readers to identify main topics and subtopics, which is essential for organizing notes effectively.
While the other features like multimedia and graphics, connections and distinctions, and figures and tables can enhance understanding and retention of information, they do not directly contribute to the outlining process in the same way that headings and subheadings do.
