Answer: The lather was drying on his face. I must hurry. Through the mirror, I took a look at the street.
The pace of a narrative is the speed at which a story is told. It depends on the length of the events and how fast the action moves. In a fast-paced narration, the reader is provided with information more quickly.
In this case, excerpt 2 tells us the details of how the man waited for the lather. In excerpt 3, we find out how the man slowly got ready to sit down. Excerpt 4 details how the man moved the chair. They are all slow descrrptions. On the other hand, excerpt 1 tells us that the man is in a hurry, that the lather was drying and that the narrator looked out the window, all in a short space of time.
