Answer:
The structure of the text allows the reader to perceive a range of equipment that is not working properly and therefore prevent the good work of the firefighters.
Step-by-step explanation:
Textual structure refers to the way the text is organized and how the information is presented to the reader. There are many types of textual structure, among which, we can mention the sequential structure, which is the one that presents a sequence of elements that have been part of a narrative. In the case of the text above, we can see that the author decided to use this type of structure, since we can read a sequence of equipment, used by firefighters, which are malfunctioning. In addition, we can see that this malfunction promotes a series of negative events that prohibit firefighters from doing a good job. These effects are also presented sequentially.
