Final answer:
The question appears to contain an error, as all the given options (Cause and Effect, Problem and Solution, Compare and Contrast, and Chronological Order) are recognized non-fiction expository text structures. Therefore, none of the provided options is incorrect.
Step-by-step explanation:
In expository writing, there are several recognized organizational patterns or text structures. These include Cause and Effect, which explores why things happen and the results of these events; Problem and Solution, which identifies a problem and then presents one or more solutions; Compare and Contrast, which discusses the similarities and differences between two or more elements; and Chronological Order, which arranges information according to the sequence of time.
All of these are commonly used structures within non-fiction texts. However, one must discern which organizational pattern is not traditionally categorized under the five non-fiction expository text structures. The options given are all recognized structures, so none of the given options is incorrect. Therefore, there might be an error in the question as it assumes one of the options is not an expository text structure when in fact they all are.
