Dear Professor M,
I hope this message finds you well. As I was reviewing the assignment, I encountered a bit of confusion regarding the terminology used in questions 1-5. Some questions specifically mention "your principal industry," while others simply refer to "your industry." I assume that both terms are intended to refer to our principal industry, as the term is not pluralized, but I would like to confirm this to ensure my understanding is correct. Additionally, question 2 does not specify which industry to focus on at all.
Thank you for clarifying this matter.
