Who told Margie about the old school?

Correct answer: Tommy did

The governing concept is identifying the speaker who provides important information about the past educational system. Tommy reads the printed book and explains to Margie that children once went to a special building called a school, studied together and were taught by a human teacher. Therefore, option A is correct. The County Inspector only examines and adjusts Margie’s mechanical teacher; he does not describe the old school to her. Her mother is concerned with her lessons, and no neighbour performs this role. Tommy’s discovery and explanation lead Margie to imagine the social pleasures of old-fashioned schooling.
