Which of the following is true about correlation and causation? a. two events that happen at the same time cannot be causally related or correlated. b. historical narratives can be built around correlated events, but not causal relationships. c. studying causation provides a clearer picture of historical events than studying correlation. d. determining causation is a necessary step historians take before proving correlation.

C. Studying causation provides a clearer picture of historical events than studying correlation.

Correlation occurs when two events happen at the same time. On the other hand, causation refers to an event being the cause of the second one. Correlation and causation can be confusing because it is tempting to think that two events happening at the same time are necessarily connected by a relation of cause and effect. However, when causation is indeed present, it provides a clearer picture of historical events than correlation.

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
