Sometime after the year 2000 B.C., a group of people known as the Aryans invaded parts of modern-day India. They came from an area of Central Asia near the Caucasus Mountains, moving southeast and eventually taking over the entire Indus Valley. They spoke a language called Sanskrit, which became the basis of many modern South Asian languages. Much of what we know about them today came from sacred writings called the Vedas. The Vedas are mostly religious texts, but they also describe famous victories of the Aryans as they invaded India. The Vedas were also influential in the development of Hinduism, which is one of the world's oldest religions. Based on the information in the passage, which of the following is most likely true? A. People in South Asia were forced to adopt the Aryan culture as their own. B. Aryan culture was only influential in the immediate areas they conquered. C. Much of India's present-day society was based on the Aryan civilization. D. Indian society reached its highest point just after the Aryan invasion.
