It is false that in-text citations must be clearly identified.
What you must do is cite the author and the year. An in-text citation is a citation in parenthesis. You give proper credit to the source or author, informing the reader where it can find more information. For instance, APA in-text citation uses the last name of the author and the year of the publication. If it is a direct quote, include the page: (Moore, 2018, p. 211).
