Which of the following skills is essential for critical comprehension?

Identifying the main idea and supporting details is crucial for critical comprehension because it enables readers to grasp the central argument or message of a text. This skill allows individuals to evaluate how supporting details reinforce or elaborate on that main idea, aiding in the overall understanding of the material. By effectively identifying these elements, readers can engage in deeper analysis, assess the validity of arguments presented, and make informed judgments about the content. This not only enhances comprehension but also encourages critical thinking and reflection on the text's implications and significance.

Memorization of facts might aid in recalling information, but it does not foster understanding or analysis. Focusing on personal opinions could lead to bias and may prevent an objective interpretation of the text. Summarizing read texts is a useful skill, but it typically comes after the ability to identify main ideas and details, as effective summaries depend on those foundational skills.
