Answer:
elizabeth --> spatial
charity --> categorical
robert --> compare-contrasat
kent --> chronological
Explanation:
elizabeth is spatial because since she's describing a campsite, and the spatial organizational structure (also known as descriptive writing) is when you describe something.
charity is categorical because since she wants to sort ideas into groups, she can use categories to do so. in different cateogries, she can put similar things together.
robert is compare-contrast because since he wants the audience to decide between two options, the best way to show that two choices is by comparing and contrast them. (example: how the choices are similar, how they are different)
kent is chronological because since he wants to provide steps, it is best that he writes in chronological order (step 1, step 2, step 3...) which would make it easier for the audience to follow the steps
