What advantage does skimming a passage provide?

Skimming a passage is primarily beneficial because it enables readers to quickly identify the main ideas and general themes without getting bogged down in every detail. This technique is useful when time is limited or when a reader is trying to gain a quick overview of the content. By focusing on key phrases, headings, and the overall structure of the text, skimming allows for rapid comprehension of the essential points being conveyed. This approach is particularly valuable in educational settings, where understanding the main themes can inform more detailed reading and analysis later on.
