Why does the criticism of technology in the story not seem exaggerated?

Correct answer: Because the story shows both the usefulness and weakness of the machine

The governing principle is balanced evaluation. A criticism is convincing when it acknowledges both the strengths and the weaknesses of the subject being examined. In the story, the mechanical teacher is useful: it delivers lessons at home, gives regular tests, and can be adjusted when its geography or arithmetic section causes difficulty. At the same time, it isolates Margie and cannot reproduce the warmth, cooperation, and shared enjoyment of a human classroom. Thus option C is correct. Option A is false because the usefulness is clearly shown; B is too one-sided, and D contradicts the entire setting of the story.
