Which double impact of technology does the mechanical teacher show in the story?

Fast learning and human distance

The governing concept is the dual effect of technology: it can increase efficiency while reducing direct human interaction. The mechanical teacher makes instruction organized and relatively fast. It presents lessons, checks answers, and can be adjusted to Margie’s level, so it represents the practical advantage of individualized automated learning. At the same time, Margie studies alone and misses the companionship and shared happiness of a traditional classroom. This creates human distance even though the machine performs its instructional duties well. Option A correctly combines both sides of the effect. Options B, C, and D mention only unrelated or incomplete ideas: the story does not present machine education as only joyful, old books are a contrast to technology, and school-building growth is not discussed.
