听力原文：I want to discuss the changes in assignments and reporting that will go into effect October first. First of all, your team won't be reporting to Lisa any more. Rebecca will be your new supervisor. Lisa will still be working with your team, but she's not going to be involved with the day-to-day details or schedules of any of your projects. Her focus is going to be on expanding our client base and creating more revenue. The second change is a shift of resources within the team. Let me give an overview and then we'll go into details. First, Carol and John are going to take over the Slavin Project. This will free up Steve to be a co-lead on the Talon Project with Marcia. Robert and Wendy, you'll both remain on your current projects in your current roles. I'm sure you all have a lot of questions, and I'll do my best to try and answer them.
What is learned about Rebecca？

A. She has retired from the company.
B. She will be the new team supervisor.
C. She will have to leave the meeting early.
D. She has been working closely with Carol and John.
