Answer:
The author used a descriptive structure, composed of dark and frightening words.
Explanation:
The author used a descriptive structure, where he can put words of a dark and frightening tone to describe the scenario and the feelings of the narrator in relation to the situation he was experiencing. Like the narrator, the reader does not understand what is happening, nor does he even have a perspective on what will happen, but he maintains a feeling of unpredictability and that something can arise at any time, that is, a sense of suspense.
