The absence of human teachers reveals which limitation of technological progress in the story?

Progress cannot automatically replace human sensitivity

The governing concept is the difference between technical efficiency and human understanding. The mechanical teacher can display lessons, assign work, and check answers, so the story does not claim that technology is unable to teach at all. Its limitation is that it cannot automatically provide empathy, flexible encouragement, social interaction, or a sensitive response to a learner’s feelings and difficulties. Hence option B is correct. Option A is factually contradicted by the machine’s functioning, option C reverses the solitary arrangement, and option D presents an extreme claim that the story never makes. The lesson supports balance, not blind rejection of technology.
