Which of the following are not pastoral nomads?

Pygmies are not pastoral nomads. Pygmies are nomadic peoples living in the equatorial rainforests of central Africa, with smaller numbers in south-east Asia. They are characterized by their short height (below 1.5 meters, or 4.5 feet, on average). They prefer their specific ethnic names, such as Baka or Mbuti, rather than the generic "pygmy."
