I am not so sure what you are asking
For the first red, you don't need an article before "relationship".
When you're saying "type of [word]", do not put any article before that word.
Example: "a type of device"
Not too sure about the "your back" parts. It could be your teacher does not like repition.
Also not too sure about "did". He probably wanted you to use the word "felt" instead of "did feel"
The first word of the last paragraph should be "in" not "at".
The red commas definitely do not need to be there.
Don't know why he marked "time to" and "to" red.
Of these four words, the one which is most likely to have a negative flavor or connotation is d)meander. To confuse is the state of being bewildered or unclear in one's mind about something. To distract is to the divided attention of an individual or a group away from the designated object on which the focus should be put on. A harangue is a long speech delivered in front of an audience. To meander is to walk around aimlessly without a fixed direction which contains a negative flavor or connotation.
BAHAH I CANT WITH THIS ONE
