I am in talks with a PhD supervisor for admission to university who likes my profile but has given me an article to review. Although the article is related to my broader research area, there are some terminologies that I don't have proper background knowledge. I have read the article and have fair understanding of it. I have written a summary, problem statement, proposed solution and methodology in review format provided by supervisor but I am stuck at critical review section as I don't have proper background knowledge. I want to know how to go about in this case? How should I review this critically?
Any help would be appreciated.
