Read the following passage carefully and answer the questions that follows.

In the areas where tribal populations are concentrated, their economic and social conditions are usually much worse than those of non-tribals. The impoverished and exploited circumstances under which adivasis live can be traced historically to the pattern of accelerated resource extraction started by the colonial British government and continued by the government of independent India. From the late nineteenth century onwards, the colonial government reserved most forest tracts for its own use, severing the rights that adivasis had long exercised to use the forest for gathering produce and for shifting cultivation. Forests were now to be protected for maximising timber production. With this policy, the mainstay of their livelihoods was taken away from adivasis, rendering their lives poorer and more insecure. Denied access to forests and land for cultivation, adivasis were forced to either use the forests illegally (and be harassed and prosecuted as 'encroachers' and thieves) or migrate in search of wage labour.

The land of Adivasis was captured for which of the following reasons by the Government of India?

Development of Mining and Dam projects

The correct answer is Option (4) → Development of Mining and Dam projects

"After the Independence of India in 1947 the government’s monopoly over forests continued. The policy of capital-intensive industrialisation adopted by the Indian government required mineral resources and power-generation capacities which were concentrated in Adivasi areas. Adivasi lands were rapidly acquired for new mining and dam projects. In the process, millions of adivasis were displaced without any appropriate compensation or rehabilitation. Justified in the name of ‘national development’ and ‘economic growth’, these policies  were also a form of internal colonialism, subjugating adivasis and alienating the resources upon which they depended. Projects such as the Sardar Sarovar dam on the river Narmada in Western India and the Polavaram dam on the river Godavari in Andhra Pradesh displaced hundreds of thousands of adivasis from their original habitats. These processes continue to prevail and have become even more powerful since the 1990s when economic liberalisation policies were officially adopted by the Indian government. It is now easier for corporate firms to acquire large areas of land by displacing adivasis."
