Which of the following best describes the practice of skimming?

Skimming is best described as rapid reading aimed at gaining an overview of the content. This technique enables readers to quickly identify the main ideas and key points without focusing on every single detail or word. It is particularly useful when trying to determine whether a text is relevant to one's needs, allowing for efficient information gathering.

The practice of skimming involves scanning the headings, subheadings, and highlighted terms while paying minimal attention to unimportant details. This method contrasts with slow reading or detailed comprehension, which focuses on understanding every aspect of the text. Skimming does not involve reading aloud, which would be more time-consuming and not conducive to rapid content overview. Thus, option C accurately reflects the essence of skimming in the context of reading strategies.
