Rhetorical Analysis Introductions
Both introductions tell us the topic and purpose of the analysis. The introduction sets the tone for the analysis and what is to follow in the rest of the piece. It use defines the audience and provides some credentials of the writer to the topic. When introducing their topic, both authors used specific evidence straight from the original piece.
Overall, I think and introduction to a rhetorical analysis should include the purpose for writing the analysis, facts, and a thesis. It should describe the topic or issue, introduce and writer and some background on them or why the wrote on the subject. It should identify an audience and be able to identify a tone or style.
