Why is a cautious view toward technology necessary in the story?

Correct answer: Because technology gives benefits but can also cause social and emotional loss

The governing concept is balanced evaluation: a technology should be judged by both its benefits and its human consequences. In the story, the mechanical teacher offers convenient home instruction, regular testing, and adjustment to Margie’s level, so it is clearly useful. Yet the same system isolates her from classmates and human teachers, making learning lonely and reducing shared emotional experience. A cautious view is therefore necessary because efficiency does not automatically equal complete well-being or meaningful education. Option B expresses this balanced conclusion. Option A is false because the machine has genuine practical advantages. Options C and D misunderstand the setting and the historical contrast. The story encourages thoughtful use of technology rather than blind rejection or unquestioning acceptance.
