Email a Professor- Doyun Kim

This is prompt number 1:

Subject Line: Inquiry about  Homework- Doyun Kim

Hello professor, this is Doyun Kim from your Speech Communications class. I am emailing you because I’m not sure how to complete the How-To speech introduction assigned to us on Friday. The instructions seem unclear and unfortunately I’m unable to understand what the assignment is asking. What sort of format should I use for the introductory paragraph?
Thank you.
