Answer:
A. It allows the narrator to provide a boader commentary on what alkakiy’s mistreatment shows about people’s behavior.
Step-by-step explanation:
In paragraph 2, the "introduction" of the "young man, a new comer" is important to the whole passage as it allows the "narrator" to provide a "broader commentary" on what "Alkakiy’s mistreatment" shows about people’s behaviour. The mistreatment given to the man shows the how the people in the surrounding are merciless and do a cowardly behaviour. It gives the idea of the entire situation under which the young man has faced the mistreatment.
