Ome immigrants were so flustered that they could not answer. They were allowed to sit and rest and try again. About one immigrant out of every five or six was detained for additional examinations or questioning.

The writer Angelo Pellegrini has recalled his own family’s detention at Ellis Island:

We lived there for three days – Mother and we five children, the youngest of whom was three years old. Because of the rigorous physical examination that we had to submit to, particularly of the eyes, there was this terrible anxiety that one of us might be rejected. And if one of us was, what would the rest of the family do? My sister was indeed momentarily rejected; she had been so ill and had cried so much that her eyes were absolutely bloodshot, and Mother was told, “Well, we can’t let her in.” But fortunately, Mother was an indomitable spirit and finally made them understand that if her child had a few hours’ rest and a little bit to eat she would be all right. In the end we did get through.

According the passage, some immigrants were allowed to sit and rest before taking the exams again. How does the quotation from Angelo Pellegrini develop this topic?

A It provides a firsthand account from an immigrant who felt “this terrible anxiety that one of us might be rejected.”
B It provides a firsthand account from an immigrant whose “eyes were absolutely bloodshot.”
C It provides a firsthand account from an immigrant whose “sister was indeed momentarily rejected; she had been so ill.”
D It provides a firsthand account from an immigrant whose sister was given “a few hours’ rest and a little bit to eat.”
