Assuming you meant explanatory text and not exclamation text, the answer would be brackets. For example, say your quotation is "She wrote the book." If you are quoting this directly in a paper, you want your audience to know who "she" is. So, you use brackets, and write the following: "[J.K. Rowling] wrote the book." Hope this helps.
Answer:
Pink and Say is an important story about two soldiers in the Civil War: Sheldon Curtis (Say), a Union soldier, and Pinkus Aylee (Pink), a Union soldier in the 48th colored regiment. Pink finds Say wounded on a battlefield and pulls him to safety at his mother’s home. During Say’s recovery, Pink and Say spend more time learning about each other and developing a deep friendship. Eventually, the boys are caught and separated, unsure and concerned about the other’s fate. This heartwrenching story will remind families of the brutalities that took place during the Civil War. As your family experiences the account of these soldiers, you will be reminded of the great sacrifices that were made during the war. You and your child will learn more about the conditions of the Civil War, sharing rich discussions about racism, war, service, and friendship.
