Final answer:
The speaker should use the spatial pattern in a process or demonstration presentation.
Step-by-step explanation:
The speaker would be wise to use the spatial pattern in a process or demonstration presentation. The spatial pattern organizes information based on physical or geographical relationships. It is especially effective when the speaker wants to demonstrate how different elements are related to each other in a physical space. For example, if the presentation is about the layout and design of a city, the speaker can use the spatial pattern to discuss different areas and their characteristics.
