What technology-related work did the County Inspector do?

Correct answer: Repair of the machine teacher

The County Inspector’s technical task was to examine and repair Margie’s mechanical teacher. When its Geography sector began giving lessons too quickly, he visited her home, opened the machine, checked its components, and corrected the faulty adjustment. He did not replace the machine with a human teacher or build an old-style school. Thus, option A is correct. The other choices are unrelated to his role and to the events in the story. His visit demonstrates both the dependence of future education on complex technology and the need for skilled people who can maintain, calibrate, and repair educational machines when they malfunction.
