use the synthesis matrix to analyze how scientifically accurate is the original article

Need to use the synthesis matrix to analyze how scientifically accurate is the original article (daily mail). I slightly compared three other articles with the original article, but need further to say how these comparisons are related to the original content’s accuracy. Don’t just take references from the synthesis matrix file but more research from the other three articles, thanks.
