What is the purpose of headings in a passage?

Headings serve a crucial role in organizing information within a passage. They help to indicate the structure by breaking down the text into sections, which allows readers to navigate through the material more effectively. Each heading typically corresponds to a specific topic or focal point, guiding the reader on what to expect in that section. This structural aid enables readers to quickly locate information, understand the main ideas, and follow the progression of thoughts throughout the text. By highlighting the key areas, headings can enhance comprehension and retention of information, ultimately making the reading experience smoother and more efficient.
