BTW, for Bolivia, Spanish and Quechua didn't work for some reason. Bolivia has Spanish and the many other languages spoken in rural areas as its official languages:
Part 1, Title 1, Chapter 1, Article 5 of the Bolivian constitution:
"The official languages of the State are Spanish and all the languages of the rural native indigenous nations and peoples, which are Aymara, Araona, Baure, Bésiro, Canichana, Cavineño, Cayubaba, Chácobo, Chimán, Ese Ejja, Guaraní, Guarasu'we, Guarayu, Itonama, Leco, Machajuyai-kallawaya, Machineri, Maropa, Mojeñotrinitario, Mojeño-ignaciano, Moré, Mosetén, Movima, Pacawara, Puquina, Quechua, Sirionó, Tacana, Tapiete, Toromona, Uruchipaya, Weenhayek, Yaminawa, Yuki, Yuracaré and Zamuco."
Quechua is also an official language of Peru.
