The correct answer is D. Reading and writing
Step-by-step explanation:
The word monk refers to a person that has decided to dedicate his life to religion and especially to prayer and contemplation with the purpose of serving God and society. Monks can be found in a variety of religions such as Christianism, Buddhism, or Hinduism but are mainly known in the Christian context especially because during the Middle Ages monks and monastery were essential for the power of church and the preservation of documents as they wrote manuscripts to create copies of religious books and even if nowadays this is not used it is quite common monks in every religion study and read religious scriptures or text and even write about them. Also, monks were known for helping those in need and spreading the faith. Therefore, one activity hat monks probably did was reading and writing, as this was especially common between Christian monks but also in monks from other religions as reading scriptures was one of the steps to reinforce the faith and serve God.
