      I will have a test on Thursday, that question is one of my review. I answered all questions that my teachers gave me, except for that one.

      And can you read? (obviously redundant question since you communicate with me via writing, but I cannot imagine what other problem you could have)

      Hi The question is a bit badly worded but it appears to be asking you to name and describe as many different kinds of respiratory systems as you can think of. For instance, how do insects breathe?
