Children of the same age studying together in old schools shows which educational arrangement?

Correct answer: Class-based group system

The governing concept is age-grouped, classroom-based education. In the old system described by Tommy, children of a similar age went to a school building and studied together under the guidance of a human teacher. This arrangement forms a class or group in which learners can interact, work at a common level and share classroom experiences. Therefore, option A is correct. Option B describes Margie’s isolated home education, not the old system. Option C also refers to the future mechanical arrangement. Option D is false because old schools had human teachers. The detail about children of the same age is important because it identifies a conventional class structure rather than individual instruction.
