The correct answer is - The region is dominated by desert and high elevations.
Most of the population of China is concentrated in the eastern half of the country, while the western half is very sparsely populated. The main reason for this is the geography and the climate of this part of China.
The western half of the country is dominated by high mountains, the highest in the world actually, the Himalayas, the Tibetan Plateau, deserts and semi arid ares. All of these places are not suitable for living, especially not for larger populations, so there's towns and villages that far away from one another, and they have relatively small populations.
I believe it because they give people a sense of belonging to a certain community.
Rather than tied solely to religious aspects, Judaism followers treated each other like they're belonged to a close family (they are taught a similar culture, way of life, way to behave, etc.)
This type of sense belonging was really powerful since humans are naturally created to work as a group rather than following individualistic pattern.
