What method would help in highlighting essential information while reading?

Close reading is an effective method for highlighting essential information because it involves a detailed and thorough examination of the text. This approach encourages readers to engage deeply with the material, enabling them to identify important themes, arguments, and evidence. Close reading allows one to consider the nuances of language, structure, and context, leading to a better understanding and retention of the crucial elements of the text.

By analyzing the choices, actively taking notes also promotes engagement but does not necessarily involve the same level of depth as close reading. Skimming fast may help in getting a general overview of the material but often results in missing key details. Using visual aids can complement understanding but is not inherently focused on the reading process itself. Thus, close reading stands out as the method that most directly facilitates the highlighting of essential information.
