In machine education, on what does the student's dependence increase most?

Correct technical setting and machine operation

The governing concept is technological dependence in a machine-controlled learning system. When lessons, tests, and feedback are delivered by a mechanical teacher, the student must rely on correct programming, settings, and operation for the system to function properly. In the story, a problem with Margie’s geography lessons is traced to an unsuitable setting, and the County Inspector adjusts it. Thus option B is correct. Option A would belong to collaborative classroom learning, not isolated machine instruction. Option C is a physical school facility, and option D represents a human educational resource that the system has largely removed. The question therefore measures dependence on technical control rather than dependence on social or traditional support.
