In the novel “Hard Times” by Charles Dicken, Mr. Gradgrind refers to Sissy as “girl number 20”. Charles uses this labeling of Sissy to criticize the dehumanization of students and the stripping away of their individuality.
Mr. Gradgrind is so unbiased that he doesn't use names when referring to his students, instead he uses numbers like he does with Sissy.
The last one
Hope this helps
