What does Margie's mechanical teacher symbolize?

Correct answer: Technology-dominated education

The correct answer is B because Margie receives lessons, tests, and corrections from a machine rather than from a human teacher. The mechanical teacher represents a future in which education is organized around programmed instruction, individual home study, and technological control. It is efficient in some tasks, but its presence also emphasizes Margie’s isolation and her lack of ordinary classroom companionship. Option A is unrelated to the futuristic setting. Option C is too narrow because the machine teaches several subjects, not art alone. Option D has no connection with the lesson. Thus, the symbol combines technological progress with a question about whether efficiency can replace human warmth and shared learning.
