As seen by the clothes...these ain't typical New York schoolgirls; but privately schooled girls of Hasidic Judaism; within which women are organized in the harem system. Not the harem system showed to goyim about satisfying the lust of few men with the offering of many women, but as a harem/haram (safeguard). In such a place...women of all ages are teaching one another how hygiene; breeding; husbandry etc. work.

The tunnel angle for the goyim imagination is about scared kids lost in the darkness, while the jewish angle is about protecting jewish eugenics from the eyes of gentile disgenics. If you promote miscegenation to the united states of gentiles; then having a bunch of segregated/apartheid breeding operations out in the open may offend the amalgamated masses sweating in the melting pot.
