Which aspect is crucial for understanding expository texts?

Understanding expository texts requires a solid foundation of previous knowledge on the topic being discussed. This background knowledge activates relevant schema in the reader's mind, allowing them to grasp concepts more easily and make connections to information presented in the text. Familiarity with the subject matter facilitates comprehension, as the reader can fill in gaps and better understand new information in context. Without this prior knowledge, the reader may struggle to make sense of the material and fully engage with the arguments or explanations provided. Thus, previous knowledge is a critical component for effective reading of expository texts, as it enhances overall understanding and retention of the information.
