Why is comparison between mechanical teacher and human teacher important to understand technology's impact in the story?

Correct answer: Because it shows the difference between machine speed and human interaction

The comparison is important because it presents both the strength and the limitation of educational technology. A mechanical teacher can deliver lessons quickly, follow a programmed schedule, adjust work to a learner’s level, and check answers efficiently. A human teacher, however, can communicate naturally, notice emotions, explain confusion in flexible ways, encourage a child, and build a social relationship. Therefore, option A is correct: the contrast reveals the difference between machine speed and human interaction. Option B is false because the two systems are not identical. Option C reverses the story, since the human teachers belong to the earlier school system rather than living on screens. Option D is contradicted by the machine’s regular lessons. Understanding this comparison prevents a one-sided view that treats technology as either wholly good or wholly bad.
