Question

List at least three examples of imagery in the text that add to the overall tone. Explain how each description contributes to the emotional power of the piece.

Answer 1

Do you have an example of the "text"? It's difficult to answer a question like this without seeing the text itself.
Main pieces of imagery can be something describing how stuff looks, smells, feels, or what it sounds like. It should create a picture in your head. So whatever helps illustrate the text for you is an example of imagery! Hope this helps!
