Final answer:
The spread of Buddhism resulted in the influence on social structures, opposition to the caste system, and the establishment of Buddhist institutions.
Step-by-step explanation:
One result of the spread of Buddhism was its influence on social structures. Unlike Hinduism, Buddhism did not emphasize the caste system and often opposed it. This appealed to lower-caste individuals and led to the spread of Buddhism in Southeast Asia, China, Korea, and Japan. Buddhism's egalitarian ethos and emphasis on charity also attracted followers and led to the establishment of Buddhist institutions that played a significant role in providing services, such as charity, building roads, and running shops.
