I agree with people above that the survey is based on people looking at languages for fun.
Mongolia --> Korean?? Would make much more sense for it to be Chinese
Papua New Gineau --> Spanish?? Seems strange.
India --> English?? Yup, as other have said. It is interesting that on their money, they have the written denomination in 14 (I think languages). Most people, especially in the south, are against Hindi as a language, so you dont see that much in that area. When i was in Tamil Nadu, there was some push at the national level to have people learn Hindi. Lots of signs and graffiti posted that said "English Ever, Hindi never"
