Which of the following types of speech arrangements would be most appropriate for topics such as "the evolution of the modern automobile"?

The most appropriate type of speech arrangement for a topic like "the evolution of the modern automobile" is temporal arrangement. This method organizes the content chronologically, breaking down the topic into a sequence of events or developments over time.

When discussing the evolution of the modern automobile, it is crucial to highlight major milestones, technological advancements, or historical changes in the automotive industry. A temporal arrangement allows the speaker to effectively guide the audience through the journey of the automobile's evolution, from its early beginnings to its current state, while maintaining a clear and logical flow.

The other types of arrangements—spatial, topical, and inquiry—are less suitable for this specific topic. Spatial arrangement focuses on a physical layout or geography, which doesn't directly apply to the historical context of automobiles. Topical arrangement would break down the subject into categories, which could work but may not emphasize the chronological development as effectively. Inquiry-based arrangements typically revolve around investigating a question, which is not the primary aim when outlining the evolution of a specific subject over time.
