Which year does Margie write in her diary?

Correct answer: 2157

The governing concept is the futuristic time setting of Isaac Asimov’s story. Margie begins her diary entry on 17 May 2157, so the correct year is 2157, given in option B. The other years are distractors: 2057 and 2257 do not match the date stated in the narrative, while 1957 belongs to the past relative to the story’s setting. Identifying the year helps readers understand why mechanical teachers, home classrooms, and screen-based lessons seem normal to Margie. It also creates the contrast that makes the discovery of a printed book and an old-style school surprising to her.
