The correct answer is 2. "First class!" my mother exclaimed, with an intake of breath. "How did you end up there?" ...
Step-by-step explanation:
In excerpt two, there is a clear contrast between the mother of Hemma (female main character and narrator) who belongs to a middle or low socioeconomic status and the parents of the male character Kaushik. This is shown by the reaction of the mother of Hemma who is shocked by the extravagance of flying in first class. This is shown in "First class!... How did you end up there?" that shows the surprise of the mother and the answer of the father in "It could become a terrible habit" that shows how proud he is of this event. Thus, this excerpt shows the diversity within socioeconomic status by explaining the shock and surprise of Hemma mother to the fact another family flew in first class.
