Hello. You did not enter the text to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
The text structure refers to how the text was organized and how the information contained in it was presented. To discover the textual structure, it is necessary that you read the text. However, we know that the structure used was intended to persuade readers. Thus, we can consider types of structures capable of convincing readers about the author's point of view and opinion on the subject addressed in the text.
The best textual structures to promote persuasion are the structures: descriptive, cause and effect, or, problem and solution.
The descriptive structure is one in which the author's positioning is addressed through the description of a concept, showing what this concept has to be correct. The cause and effect structure shows how an element is capable of causing the existence of another element. Finally, the problem and solution structure is able to show how problems were solved and the process for solving them.
