01 What could the mechanical teacher not give Margie?
Answer and explanation
Correct answer: B. Social and human learning
Explanation: The correct answer is B because the mechanical teacher could deliver regular lessons and tests but could not provide the social and human experience of learning with others. Margie’s machine was programmed to teach her at home, measure her progress, and give exercises. However, it could not replace friendship, group discussion, emotional encouragement, or the feeling of belonging to a class. Option A is not something the machine was expected to provide, while C and D were among its functions. The governing contrast in the story is between efficient individualized instruction and the warmth, interaction, and understanding associated with human classroom education.
