Read the following passage carefully and answer the question that follows:
In the case of the Adivasi, the future is the enemy of the past. The forces of modernization are rapidly wiping out Adivasi cultural tradition. The economic marginalization of the Adivasis is seen as a result of something inherent in their traditions and social structures, and not a consequence of historical and legal interventions issuing out of colonialism. The ignorance about social structures, world-views and cultural practices of the Adivasis is quite pervasive. We have not made even the slightest progress in the direction of understanding Adivasi art and literature in India. Most of our literary critics and art historians remain innocent about the existence of Adivasi art and literature. However, the art and literature of Adivasi communities in India have their own peculiar identity. When we look at them as strangers, our response to them is trapped in quasi-anthropological parameters. Lacking the patience and inclination to understand them on their own terms, we hurriedly conclude that these are art forms which have merely fallen out from mainstream Indian society and have remained frozen in some remote historical time.
