Fagan is trying to convince an audience about the benefits of a new cleaning product. He wants them to understand what it does and that it's the best product out there. He only has this opportunity to change their attitudes about the product. He plans to show a product demonstration that he hopes the audience will enjoy. He realizes he demonstrationi is a bit misleading, but he is convinced it's for the audiance good and to try the product. What unstated assumption can we make about Fagans speech?
