What did Buddhist monasteries provide people?

B:Social Services

Explanation:

I looked at the transcript and it says "Monasteries didn't have to pay taxes and provided important social services, like taking care of the sick, giving seeds to farmers, and helping the poor, and running schools."

(d) rivers.

explanation:

civilizations developed around rivers because their waters provided places to hunt and fish. also, as the rivers flooded, the lands around them became fertile. this allowed them to support farming. this is especially true of the nile river, which flooded the same time each year.
