Well, when writing a response to any subject or question, you first have to have a clear understanding of what is being asked. If the nature of the questions isn't clear, you should ask the inquirer some questions of your own: To what exactly are they referring? Did I not explain something clearly enough to them? Are they confused about what is required of them? Do they not understand the message the author is putting across? Have they learned to "read between the lines" and interpret symbolism?
All these are questions that need to be addressed when writing a response to literature.
