Questions 147~148 refer to the following email. Dear IHEE Human Resources Manager,
I am writing to inform you that Ms. Emily Wong, the original author of the book "Efficient Supply Chain Management", will unfortunately be unable to attend the upcoming intermediate staff training day on the 15th of next month. Due to a significant illness in the family, she has had to travel to Canada and will be unable to make the journey back in time for the event.
However, I would like to offer myself as a replacement speaker for the event. As a co-author of the book, I am intimately familiar with its subject matter, which focuses on optimizing supply chain efficiency, and I would be happy to give a 90-minute talk on the topic.
Thank you for your understanding and consideration.
Sincerely,
Mr. David Lee, Co-author of "Efficient Supply Chain Management"
