research paper need 800 - 1000 word review

Once you have finished reading the article, select a second article from the references in the first article or closely related to the topics in the first article and then write an 800 - 1000 word review of the two articles (combine the two reviews; do not write two separate reviews) in an R Markdown document. What are the main issues they address? How are the two article connected? List three things that you learned or three key take-aways (from either of the two papers). Are there statements that you do not agree with?
