Which plant was native to the old world? a) rose b) tobacco c) cotton d) marigold

D) marigold

Explanation:

Despite the large number of names with which this species is known, nobody knows for sure where it actually comes from. It is assumed that the Mediterranean area of Europe and that in all likelihood is nothing more than the result of the crossing of other species of the genus Calendula, perhaps of C. arvensis, the wild wonder, and some other.

It is a plant that has been used in the Mediterranean region since the time of the ancient Greeks, and was previously known by Hindus and Arabs for its therapeutic qualities as a medicinal herb as well as a dye for fabrics, products of food and cosmetics, although many of the popular uses attributed to it have not been scientifically proven.

the caste system in india is the paradigmatic ethnographic example of caste. it has origins in ancient india, and was transformed by various ruling elites in medieval, early-modern, and modern india, especially the mughal empire and the british raj.it is today the basis of educational and job reservations in india.it consists of two different concepts, varna and jati, which may be regarded as different levels of analysis of this system.

the caste system as it exists today is thought to be the result of developments during the collapse of the mughal era and the british colonial regime in india. the collapse of the mughal era saw the rise of powerful men who associated themselves with kings, priests and ascetics, affirming the regal and martial form of the caste ideal, and it also reshaped many apparently casteless social groups into differentiated caste communities.the british raj furthered this development, making rigid caste organisation a central mechanism of administration
