How is the lack of human relationship shown in Margie's education?

She studies alone with a machine and has no classmates

The governing idea is that relationships are created through interaction and shared participation. Margie's education takes place in a room at home, where the teacher is a machine programmed to give lessons and tests. She does not meet classmates, exchange ideas face to face or experience the ordinary cooperation and friendship of a classroom. This arrangement makes learning private and efficient but emotionally isolated. Option A is correct because it gives both evidence points: solitary study and the absence of classmates. Option B is factually opposite to Margie's situation, since she does not attend the old school; option C does not establish a lack of relationship; and option D is also opposite, because the story does not present her class as crowded. The answer must connect physical isolation with missing human contact.
