Because of the mechanical teacher, what had studying become like for Margie?

Correct answer: Regular and alone at home

For Margie, studying had become a regular but solitary activity carried out at home. The mechanical teacher followed a timetable and delivered lessons every day, yet Margie had no classmates sitting beside her. Therefore, option A is correct. Option B is wrong because she did receive lessons according to a schedule. Options C and D describe situations that do not occur in the story. The important concept is the mixed effect of educational technology: it offers continuity, convenience, and individualized instruction, but it can also remove the social atmosphere of a classroom. Margie’s later interest in old schools shows that she longs for shared learning even though her machine-based education is technically organized.
