[单项选择]From: Lionel Berman
To: Vanessa Pim
Subject: A problem
Dear Ms. Pim,
I’m emailing to inform you that the service elevator is currently out of order. It stopped working at 9 am this morning while moving firm employees were transporting some new desks and chairs to the 14th floor.
At present, the workers are using one of the main elevators in the building. But this temporary solution is not ideal for two reasons. Firstly, it is not a good image to present to clients visiting the building. It looks very disorganized and unprofessional. Secondly, it may cause some damage to the main elevator. Not only might the movers scrape and scratch the interior, but there are some painters coming at 2 pm today to work on the renovations on the second floor, and they may drop paint and other chemicals inside.
Accordingly, I think it is essential that we get the service elevator working again as soon as possible. I have called the elevator maintenance firm, and the representative
A. An unprofessional employee
B. A changed moving schedule
C. A delayed construction project
D. A broken down amenity
