Two or more paragraphs that explain and develop a complex key idea are called an extended response. In an extended response, the writer provides a detailed analysis, interpretation, and discussion of a central idea or topic, supported by evidence and examples. This type of writing enables a thorough exploration of the key idea, allowing for a more in-depth examination and understanding of the subject matter.
