From what did human teachers in old schools save children?

Correct answer: From completely lonely study

The governing idea is the social nature of traditional education. Human teachers in old schools did not make children study in complete isolation; they taught groups of learners in a shared classroom. In that setting, children could see one another, speak, cooperate, and respond to a teacher. Therefore, option C is correct because such teachers saved children from completely lonely study. Options A, B, and D are not problems from which children needed saving. Studying together, human dialogue, and classroom experience were positive features of old schooling. The wording may seem slightly unusual, but the intended contrast is clear: Margie’s mechanical education is solitary, whereas the old system brought teachers and classmates together. This social setting is what makes the old schools seem enjoyable to her.
