You are giving a talk at a student conference next month. The organisers have written to say that your talk has been moved from Friday morning to Thursday evening, and that it has been shortened from twenty minutes to twelve. Write a reply to the conference secretary.

In your email, do the following:

• Say which of the two changes you are able to accept.
• Explain the difficulty that the other one creates.
• Ask for one particular thing that would make it workable.

Write as much as you can, in complete sentences.
