Final answer:
To clarify the slide information, Salina should add a title, use a clear list format for the complex data, and potentially reduce the font size of source information while ensuring the slide's learning objectives regarding poverty rates and economic inequality are incorporated into the content.
Step-by-step explanation:
To revise the slide information and make it more clear to the audience, Salina could incorporate a couple of edits. First, including a title at the top of the slide would help frame the context of the presented data regarding poverty rates and food access. Second, simplifying and organizing the complex information in a bulleted or numbered list, along with highlighting key terms, would make the slide more digestible.
For the source information, it's appropriate to keep it at the bottom, but it might benefit from slight downsizing in font to clearly separate it from the main points of the slide. These changes facilitate the audience's understanding of the criteria defining food deserts and the correlates of economic inequality.
Learning objectives such as 'Explain economic inequality and how the poverty line is determined' or 'Analyze the U.S. poverty rate over time' could be smoothly integrated into the slide's content by being clearly stated at the beginning or end of the presentation to shape the presentation's narrative and ensure these objectives are met.
