I have uploaded my paper below. I need to add 4 more pages to Discussion section

I have uploaded my paper below. I need to add 4 more pages to Discussion section and 1 page of Conclusion.
Based on the results and what is already written in Discussion you can just continue and add 4 more pages and 1 page of Conclusion. Do not change anything what is above Discussion.
The information can be taken from another additional file (Lit review.), you only use this file for the discussion or conclusion part. You can copy anything from there with all the citations, you don’t have to change words or anything. In this file there are 15 different articles reviewed and I just want to compress it all in 4 pages to support my findings. I want to have a little bit of each.
