Read the excerpt from Immigrant Kids, and then answer the question. 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.

What best paraphrases the central idea of the excerpt?

A strong mother helps her daughter and the rest of her children get through the Ellis Island exams together.
A mother and daughter are fortunately strong and pass the exams to get a few hours’ rest.
A sick young girl is not allowed through Ellis Island because her eyes are red and bloodshot.
A mother has a strong spirit and is able to get her family a little to eat so they would sleep.
