Explanation:
The first settlers of Vanuatu and Tonga arrived from northern Philippines and Taiwan between 2,300 and 3,100 years ago. DNA extracted from the skeletons found at two archaeological sites on the islands confirm this. It also suggests that the first settlers ma have by passed Papua New Guinea and Australia.
The reason behind their migration is still unknown. Some anthropologists argues that the people from islands of Asia mixed with the people of Papua New guinea, Australia and Solomon Islands while other claim that they went straight to islands such as Tonga.

Explanation:
The correct answer is - D. The arid climates cannot support farming.
The South Asia region is a region where the people, as well as the economy of the countries, are still mostly based and dependent on the agriculture. Because of this, the people have been settling in places that are suitable for farming, like the river valleys, and the regions that are under the influence of the monsoons.
The arid regions, on the other hand, are not densely populated, instead they are very sparsely populated. The main reason is that this places have high temperatures throughout most of the year. The precipitation is very rare and in very small amounts. The soil is of bad quality. All of that makes the arid places not suitable for farming, thus the people avoid them because they can not do the activity from which they depend for food and finances.
