Why are human teachers remembered in the story?

Correct answer: Because they bring human touch to education

The correct answer is B because human teachers add a personal and emotional dimension to education. In Isaac Asimov’s story, Margie and Tommy study alone with mechanical teachers, which provide lessons and tests but cannot create the warmth of a shared classroom. A human teacher can notice a child’s confusion, encourage effort, answer questions with patience, and make learning feel meaningful. Option A is irrelevant because cost does not explain why teachers are remembered. Options C and D contradict the idea of teaching. Thus, the governing concept is the value of human connection, guidance, and sympathy in learning.
