Which statement is most balanced while understanding the importance of human teachers in the story?

Correct answer: Technology is helpful, but the human role of teachers is different

The governing idea is balance rather than an absolute rejection or worship of technology. In the story, the mechanical teacher can deliver lessons, test Margie, and organise instruction efficiently. However, it cannot provide the companionship, spontaneous discussion, emotional understanding, and shared classroom experience associated with human teachers. Option A is therefore correct because it recognises both the usefulness of technology and the distinct value of human guidance. Option B is too extreme: the story does not claim that every technology is harmful. Option C is also absolute and unrealistic, since human teachers can make mistakes while still responding thoughtfully. Option D is false because machines can provide information and practice. The contrast in the story is between efficient programmed instruction and fuller, more social learning.
