Hello. You did not provide the text to which this question refers, which makes it impossible for me to answer your question exactly, but to help you, I will show you all types of textual structure and show you how to recognize them. I hope this helps.
Descriptive structure: In this type of textual structure you will see that the author is describing something, showing all the characteristics and details that make up something or someone, in a very detailed way, making the reader visualize an image through the words.
Cause and effect structure: This type of text presents one (or more) elements that were created from another element, that is, this text structure shows the consequences or the acts of things that happened
Problem-solution structure: It is used when the text shows how a problem happened and then tells how it was solved and what the consequences it caused.
