Final answer:
Margaret Atwood employs rhetorical techniques like repetition, parallelism, signpost language, visual rhetoric, and pathos in her speech to engage the audience and illustrate her ideas in an emotive and structured manner.
Step-by-step explanation:
Atwood utilizes a variety of rhetorical techniques in her speech to illustrate her ideas and intentions. Some key techniques include repetition, which is used to emphasize important concepts by reiterating words or phrases. This device is often found in notable works such as F. Scott Fitzgerald's 'The Great Gatsby', where a motif, like the green light, is mentioned multiple times to highlight its significance. Additionally, parallelism is employed to create a sense of rhythm and to reinforce a point by presenting similar grammatical structures. This can make speech more engaging and persuasive.
Furthermore, Atwood uses signpost language to guide the reader through her arguments, marking out the structure of her speech and drawing attention to particular points. Visual rhetoric, including the use of media and other visuals, can support the written text and provide additional layers of meaning. The use of technical language associated with visual rhetoric, such as 'line', 'light', and 'point of view', speaks directly to the reader in an engaging manner. Lastly, Atwood effectively weaves pathos into her speech, using emotionally charged language to connect with her listeners on an emotional level, an approach seen in the employment of words like 'decay', 'despoiling', and 'vanishing'.
