Where is the correct answer the Communication Work place- Ladder of Inference ?

There is no key to correction to show whether I have answered any of the step correctly to eventually lead to the acceptable answers. If there is a note to tell us if the step has been answered correctly then it minimizes mistakes to reoccur. and I would be led to meet all of the desired responses. What happens is that I don't know where my mistake lies that need a review of my answer because there is no validation to guide me. You don't simply say NOT GOOD! without pointing out where I did right or wrong. It will be endless and adds to frustration and loss of interest .
