A primary article can be described as an original research paper that displays new findings and information. These articles are written by the conductors of the experiment where they can display their data, methods, and results. Primary articles tend to be published as a peer- reviewed scientific journal. Each section of the article has a focus on explaining what occurred during that portion of the experiment. 

Review articles can be looked at as more refined than a primary article. They tend to be easier to understand as they provide an overall summary of the primary article. Some gather information from similar primary article to compile into one review article so readers can have a general understanding of the field. 

The peer reviewed portion process is important because, it can help give these new findings credibility. Experts in the field of the topic can help figure out what findings are useful or how it should be displayed to better digest the info. They look to see how original the work is, the way the researchers went about obtaining the work gathered and give their own feedback.

I believe the “Rapid and Sensitive Detection of SARS-CoV-2 Using Clustered Regularly Interspaced Short Palindromic Repeats” to be a primary article. The article displays sections titled “Introduction”, “Methods”, “Abstract”, all names that could be the title of a section according to Cornell university.  This leaves the second article to be the review article. My reasoning for this is that the article has been published by a journal company titled “World Journal of Clinical Cases” (WJCC).
