Final answer:
The teacher's visuals, a video advertisement and a pamphlet, aim to persuade viewers to buy a product or service, demonstrating persuasive writing techniques.
Step-by-step explanation:
The visuals provided by the teacher, a video clip of an advertisement featuring a well-known athlete promoting a brand of shoes, and a pamphlet showing damaged mobile devices to market phone insurance, best facilitate instruction about persuasive writing.
These visuals are designed to convince the viewer to take some action, such as purchasing a product or service, by appealing to emotions, credibility, or logic. The advertisement and pamphlet employ elements of visual rhetoric like arrangement, color, juxtaposition, and symbolism to create a persuasive message, effectively exemplifying the type of writing that aims to persuade.
