In the story the absence of a human teacher leads to what?

Correct answer: Margie’s loneliness

The governing idea is that education includes companionship as well as instruction. In The Fun They Had, Margie studies alone at home with a mechanical teacher. There are no classmates beside her and no human teacher with whom she can share questions, reactions, or ordinary classroom experiences. This absence makes her learning feel lonely, even though the machine gives lessons and tests. Therefore, option A is correct. A school celebration and a crowded classroom would require a social school setting, which Margie does not have. The old book is discovered and read by Margie and Tommy; it is not destroyed. The contrast helps explain why the children begin to value the older form of schooling.
