Answer:
The long, detailed sentences slow the pace and provide background information.
Step-by-step explanation:
In the excerpt from "Lather and Nothing Else," the author Hernando Tellez makes use of lengthy sentences, which give the full particulars of the circumstances existing at the time, such as how the barber makes shaving soap. Thus, the account moves slowly at the beginning, and then the suspense increases as the barber's reflections become faster and more intense.
