What reading strategy focuses on quickly engaging with text to grasp central ideas?

Skimming is a reading strategy designed to quickly engage with a text in order to identify and understand its central ideas without delving into deeper details. This method involves scanning through headings, subheadings, and key phrases to get a general sense of the content, which is particularly useful when one is trying to get an overview or when time is limited.

This technique can be especially beneficial for students or readers who need to determine whether a text is relevant to their needs before committing to a more thorough reading. Unlike intensive reading, which focuses on detailed comprehension and analysis, skimming allows readers to absorb enough information to answer questions of "what" and "why" without getting bogged down in intricate details.

In contrast, other strategies mentioned, such as revising and extensive reading, serve different purposes and do not emphasize the immediate grasp of central concepts in the same way skimming does. Revising pertains to the process of reviewing and improving a piece of writing, while extensive reading is more about reading large amounts of text for pleasure or general understanding, rather than quickly extracting main ideas.
