Final answer:
To construct a persuasive presentation on the fast-food industry's role in the obesity epidemic, establish credibility, provide reliable sources and evidence, cite using MLA format, and create a neutral, compelling argument.
Step-by-step explanation:
To create a persuasive oral presentation discussing the accountability of the fast-food industry for the obesity epidemic in America, it is essential to establish your credibility and to diligently research your topic. First, selecting a side in the argument is crucial, following which you can gather supporting evidence from articles, graphics, and alternative media formats.
You should assess the credibility of each source by considering the author's expertise, the neutrality of the language, and whether the source is respected and reliable. Such sources often include scholarly, peer-reviewed articles, professional articles and books, and mainstream media. Make sure to present evidence in its original context and to cite your sources accurately using MLA format.
Additionally, by incorporating common ground and refuting counterpoints, you strengthen the rhetorical appeal of your argument. For instance, finding an article with a neutral point of view and current, relevant statistics can support your position that the fast-food industry contributes to obesity.
