The main organizational pattern in the text is chronological order.
Step-by-step explanation:
The main organizational pattern used in the text is chronological order. This can be determined by examining the examples given in the text. For instance, the author mentions presenting a topic on World War II battles in chronological order, and discusses the causes of World War II in a different pattern. Additionally, the text provides examples of problem-and-solution and cause-and-effect patterns, which are both forms of chronological organization.
