  1. After reading the story of the family at Chusang, we can see that their life style was different than other Tibetans in that they were isolated.

  3. We can understand from the passage that the most surprising challenge for Beall was that Tibetans have surprisingly low hemoglobin levels.
  4. The miraculous response of the family at Chusang against high altitude which was quite different than the other people`s responses was that they exhaled more nitric oxide than those who live at Andes/ they had wider blood vessels.
  5. Although most of the genes which are different from one person to another stand for visible differences among people, EPAS1 was found to be quite unique for Tibetans.
  6. The first one.
  7. The third one.
