Your Solution:

You need to go back to your original document for this submission, copy and paste it into a text-only editor (e.g., notepad), and submit it once more. There are too many special characters (e.g., characters interpreted by the text form as ) for me to be able to read your responses.

It appears you have deleted parts of the original document, thereby eliminating the entire self-critique process. Since you have a large number of errors in your work, I can't tell what you do and do not understand.

I suggest you redo this assignment, and use the self-critique process as specified. If you aren't sure about this process, you should take a little time and complete Step 3 of the Orientation.
