Final answer:
Johnson's speech is structured to first contextualize contemporary challenges with history, followed by presenting his ideas through emotional appeal, and concluding with a call to national principles.
Step-by-step explanation:
The order and structure of Johnson's speech are not explicitly detailed in the provided context, making it challenging to delineate his primary points in a sequential manner without further information. However, from the context provided, we can infer some aspects of Johnson's speech organization. Johnson's speech seeks to appeal to the fears of the audience, known as pathos, a rhetorical strategy aimed at eliciting an emotional response. His references to the countryside and the schools within the broader vision of the Great Society implies these were focal topics. He evidently ends the speech drawing on patriotism by referring to the founders, as suggested by the discussion question about making their vision a reality. This suggests that Johnson layers his speech by first contextualizing current challenges within the nation's history, presenting his ideas in part through pathos, and concluding with motivational references to the country's founding principles.
