It looks like you're working on a text analysis activity where you need to fill in the blanks regarding the Response area of a paragraph. Here’s how you can fill in the blanks:
By analyzing the structure of a paragraph, you will see how the author develops and refines key concepts. A response area is an important topic for the reader to understand. Some sentences may expand, or add information to the concept. Others may elaborate, or clarify it.
So if you replace "Response area" with "structure", "expand", and "elaborate" as indicated, you will have a complete response.
