题目内容：
根据以下内容，回答题。Glenford Manufacturing, Inc.
Official Communication
From: Sean Carmichael, Operations Department
To: Irma Tucker, Sales Department Manager
The monthly sales staff meeting has been relocated from auditorium 3 to room 402. Auditori-um 3 will be undergoing repairs from April 8-15, which is why it will be unavailable for your usu-al meeting on the 10th.
Room 402 contains the same audiovisual capabilities as auditorium 3, but its seating capacity is smaller. It can only fit 65 people comfortably, whereas the auditorium can do over 100.
If this change is unacceptable, there are two alternatives. First, auditorium 2 is available on the afternoon of the 10th. It holds as many people as auditorium 3, but it has really outdated elec-tronic equipment compared to auditorium 3. And second, if the meeting is rescheduled for after the 15th, the newly refurbished auditorium 3 will be available to you.
Please contact me or another member of the operations department if you wish to change your current room reservation.
Thank you and have a nice day.
