Children learning the same things in old schools shows what?

Correct answer: Class-based common lessons

The correct answer is A because the old school described by Tommy had children of similar age learning together in a shared classroom. They followed common lessons under the guidance of a human teacher, unlike Margie’s individualized instruction at home. This detail illustrates the class-based organization of traditional schooling and also suggests cooperation, conversation, and shared experience. Option B refers to a technical problem and cannot explain a regular pattern of learning. Option C belongs to the future technological setting, while option D is the opposite of a common school. Therefore, the same lessons indicate a collective classroom system, not a machine malfunction or isolated home study.
