Children coming to one building in old schools shows which wider idea?

Correct answer: Education is a community activity

The governing idea is the communal nature of traditional education. In the old system described by Tommy, children travelled to one school building, met classmates of a similar age, learned from a human teacher, and shared ordinary experiences. Therefore option A is correct: education was a community activity, not just a private exchange between one child and one machine. Option B contradicts the description because the children left home to attend school. Option C is the opposite of the social picture, since conversation and cooperation were important parts of the experience. Option D is also false because the old schools existed before the mechanical teachers used in Margie’s time. The detail of one shared building symbolizes interaction, belonging, cooperation, and collective growth.
