Which approach is the most culturally appropriate and acceptable by the population in an indigenous village in the andes?

As there are no choices given, here is the direct answer "Provide services in local languages by providers from these villages".

The Andes, going along South America's western face, is one of the world's longest mountain ranges. Its changed territory incorporates icy masses, volcanoes, meadow, desert and backwoods etc. The mountains shield per-Colombian archaeological destinations and wild life including chinchillas and condors.
