Read this excerpt from The Circuit and answer the question. As the last days of August disappeared, so did the number of braceros. Sunday, only one--the best picker--came to work. I liked him. Sometimes we talked during our half-hour lunch break. That is how I found out he was from Jalisco, the same state in Mexico my family was from. That Sunday was the last time I saw him.

Why, most likely, does the author include this excerpt at the beginning of the story?

to foreshadow what happens at the end of the story
to minimize the surprise readers would otherwise feel to learn the family must move
to create tension about what happened to the narrator's friend
to serve as a flashback to a time when the narrator was in a better place
