I am attaching two research paper and i need 10-12 feed backs for each paper. I am also uploading the sample feedback to show you how to do it. if you open the sample file you can see that every paragraph has some feedback icon . if you click that you will see someone gives their feedback in there . So after looking at the sample you just have to open the other two papers and do the same. just make sure you are doing appropriate feedback and recommendation for that specific paper. Thanks
