Answer:
A modern hospital and an Aztec ritual.
Explanation:
Julio Cortazar's short story "The Night Face Up," tells the story of how a man got into a motorcycle accident and ends up in a hospital. At the same time, he dreams of being sacrificed in an ancient Aztec ritual which turns out to be real too. The story deals with how dreams can become a reality, through the exploration of a fantasy world.
A parallel plot is when an author uses two stories side by side to narrate or present his/ her story. These two plots share the same time and importance in the story. And in this particular story, the parallel plot is between the motorcycle accident that led the young man to the modern hospital and that very same man being made a sacrificial lamb for a ritual by the Aztecs.
Thus, the correct answer is the first option .
