How does the technical form of the mechanical teacher limit education?

It limits interaction to mechanical instructions

Option B is correct because the mechanical teacher mainly delivers programmed lessons, asks questions, checks answers, and adjusts technical settings. It can perform instructional tasks, but it cannot offer the flexible conversation, empathy, humour, encouragement, and spontaneous explanation that a human teacher can provide. Margie's learning is consequently efficient in a narrow technical sense but isolated in a human sense. Option A is the opposite of what happens, since the system does not create friendships. Option C is unsupported because it does not restore the old school system. Option D confuses the machine with the printed book that Tommy discovers. The governing concept is that educational technology may transmit content while still limiting dialogue and emotional interaction.
