The document discusses the rhetorical context of writing, which includes the author, audience, and purpose. It emphasizes that these three elements - represented in a triangle diagram - constrain all writing and should be considered in the pre-writing process. The author, audience, and purpose roles are explored in more detail, with examples provided for how to think about each element for a college writing assignment. The audience should not be seen as a "general audience" but the specific group intended to be most directly affected by the writing. Defining these three core elements can help guide writing choices.
