How did technology change assessment in the story?

Correct answer: Assessment became instant and machine-based

In the futuristic education system, the mechanical teacher does not merely present lessons; it also tests pupils and evaluates their responses. Margie’s geography work is checked by the machine, and the result is produced without waiting for a human teacher to read and mark it. Therefore, option C is correct: assessment has become immediate and machine-based. Option A is incorrect because the story describes written responses entered into the machine, not an exclusively oral system. Option B is clearly contradicted by the regular tests and poor marks Margie receives. Option D is also false because there are no classmates conducting the assessment. The episode shows both an advantage and a limitation of technology: quick, automated checking is efficient, but it does not provide the personal explanation, encouragement, or sensitivity of a human evaluator.
