Letter A is the correct answer.
Anthropologist believe that few, if any, isolated groups have existed in human history. Recently, in Brazil, an isolated indigenous tribe has emerged from the Amazon forest and made peaceful contact with villagers from the border of Peru. This indigenous tribe has got its own way of communicating and can act in a very strange way but is very much aware of the presence of outsiders.
