Consider the "5Ws & How" used in journalism to anaylze the rhetorical context of your sources. Who? What? Where? When? Why? How?
Who wrote or created the source? Look at the author(s) of the source and do a little research to learn more about their qualifications.
Who is the audience of the text? Consider who the intended audience is, as well as who are unintended audience or audiences. For example, scholarly articles are often written for professors and professionals in a given field (the intended audience), but students often read these articles for research projects, too (the unintended audience).
What message is the rhetor sending to their audience? What is the main point of the text? How do you know?
What category does the source belong to? Is it a scholarly article, a popular website article, a government report, a social media post? What format is the source in? Is it linguistic, visual, aural, gestural, spatial, or a combination of these (multimodal)?
What situations and circumstances influenced the source's publication.
Why did the rhetor make the specific argument for the specific audience?
