Final answer:
Jasper should use a problem and solution organizational structure for his presentation on the Great Pacific Garbage Patch, as it allows him to define the issue and discuss remedies in a logical progression.
Step-by-step explanation:
Jasper is creating a presentation to focus on remedies for the Great Pacific Garbage Patch. The most suitable organizational structure for this presentation would be problem and solution. This structure allows Jasper to clearly define the problem, which in this case is the Great Pacific Garbage Patch, and then explore various solutions to mitigate or eliminate this issue. By framing his presentation in this manner, Jasper can logically progress from describing the severity and causes of the garbage patch to proposing and evaluating potential remedies. Importantly, Jasper could also anticipate and address potential objections to the solutions proposed, thereby strengthening his argument.
Furthermore, this format can begin with an introduction, move on to describe the problem and then the possible solutions, possibly discuss any potential objections to these solutions, and end with a conclusion that includes a recommendation. The presentation could be bolstered by using a graphic organizer to clearly layout ideas and evidence, thus allowing Jasper to effectively communicate the urgency of the issue and the viability of the suggested solutions.
