english: But I wanted to check if this is true. So what I did last year was we hired a car, looked up on Google, found a route into northern India from New Delhi which, you know, which did not cross any big cities or any big metropolitan centers. Drove out about 300 kilometers, and wherever we found a school, administered a set of standard tests, and then took those test results and plotted them on a graph.
non_english: Chcel som sa však uistiť, či je to pravda. Takže, minulý rok sme spravili to, že sme si prenajali auto, pozreli na Google a našli cestu z Dillí smerom na sever Indie, ktorá nekrižovala žiadne veľké mestá, ani žiadne veľké metropolitné centrá. Najazdili sme asi 300 kilometrov, a kdekoľvek sme našli školu, spravili sme súbor štandardných testov. Potom sme výsledky testov zobrali a zaznamenali ich do grafu.
