David (Team Leader):

"Good morning, everyone. Let's quickly go over the plans for the new client presentation. As you know, this is a very important client, so we need to be well-prepared.

First, Sarah, you mentioned you can handle the market research slides. That's great because your analysis is always very thorough. You could also include some competitor data if you find anything relevant from last quarter's reports.

Now, regarding the technical demonstration, Mark, I know you can usually set it up very quickly. However, the new projector in Conference Room B can sometimes be tricky. So, could you please test it an hour before the meeting? We can't have any technical issues.

For the financial projections, I could do them myself, as I did for the last client, but I think Lisa might be better for this one. Lisa, can you take on the financial slides? It might involve some complex calculations, but I'm sure you can manage it. If you need any data from previous years, I could send it to you.

Finally, the overall flow. We might need to rehearse this presentation a couple of times. It could help us ensure everything runs smoothly. We can schedule a rehearsal for tomorrow afternoon if everyone is available. This client could bring us a lot of business, so let's make sure we can impress them."

Question 1: When David says, "Lisa might be better for this one," what does he mean?

💡 Hint: 'Might' indicates a possibility that David is not fully certain about.

Question 2: What is Mark asked to do regarding the technical demonstration?

💡 Hint: David asks Mark, "Could you please test it an hour before the meeting?" because the projector can be tricky.

Question 3: Complete the sentence from the audio: "If you need any data from previous years, I _______ send it to you."

💡 Hint: David is offering a possible action he can take to help Lisa.
