Why would a child be sent home in Ellis Island?
If immigrants had any of the diseases proscribed by the immigration laws, or were too ill or feeble-minded to earn a living, they would be deported. Sick children age 12 or older were sent back to Europe alone and were released in the port from which they had come. So It seems A is the right anwser.
Bān Zhāo, courtesy name Huiban, was the first known female Chinese historian. She completed her brother Ban Gu's work on the history of the Western Han, the Book of Han. She also wrote Lessons for Women, an influential work on women's conduct. She also had great interest in astronomy and mathematics and wrote poems, commemorative writings, argumentations, commentaries, essays and several longer works, not all of which survive. She became China's most famous female scholar. Hope it helps
