Answer:
YES
Explanation:
Based on the information provided within the question it can be said that in this scenario Sarai's volunteer work can be considered an exchange. Mainly due to the fact that an exchange is defined as giving something (product, service, etc.) in order to receive something in return, and in this scenario Sarai is giving her time and labor and in return is getting "a great feeling" which is of value to her.
Yup. Sarai is doing what's called "giving back to the community". The fact that she's giving back makes it an exchange.
